Chemical: Dipropylene glycol methyl ether (Dipropilen glikol metil eter) .Dipropylene glycol methyl ether (Dipropilen glikol metil eter) is a colorless liquid with a weak odor .Dipropylene glycol methyl ether (Dipropilen glikol metil eter) is an organic solvent with a variety of industrial and commercial uses.[1][2] It finds use as a less volatile alternative to propylene glycol methyl ether and other glycol ethers. The commercial product is typically a mixture of four isomers.Dipropylene glycol methyl ether (Dipropilen glikol metil eter) may react violently with strong oxidizing agents. May generate flammable and/or toxic gases with alkali metals, nitrides, and other strong reducing agents. May initiate the polymerization of isocyanates and epoxides.Dipropylene glycol methyl ether (Dipropilen glikol metil eter) (mixture of isomeres) for synthesis. CAS 34590-94-8, chemical formula (CH₃O)C₃H₆OC₃H₆(OH).Dipropylene glycol methyl ether (Dipropilen glikol metil eter) (DPGME) is one of the most commonly used propylene glycol ethers in industry and is discussed in a recently published NEG/NIOSH document.Dipropylene glycol methyl ether (Dipropilen glikol metil eter) is a collective term describing a mixture of structural isomers. In the past, OSHA has determined airborne concentrations based on a method validated by NIOSH.An examination of the Backup Data Report for the NIOSH method (Ref. 5.3) revealed that the desorption efficiency was not constant, the desorption efficiency of the individual isomers of Dipropylene glycol methyl ether (Dipropilen glikol metil eter) was not investigated, and the desorption efficiency from wet charcoal was not addressed.The reported desorption efficiency ranged from 60.4% at 2.954 mg to 89.1% at 12.01 mg of Dipropylene glycol methyl ether (Dipropilen glikol metil eter).For analytes such as Dipropylene glycol methyl ether (Dipropilen glikol metil eter), which are comprised as mixtures of related compounds, quantitation is accomplished by summing the peak areas of each component and treating the summed areas as one analyte.This is an accepted and convenient practice when using a flame ionization detector because the responses for all of the isomers of Dipropylene glycol methyl ether (Dipropilen glikol metil eter) are identical.But if the desorption efficiencies are not the same for each isomer, they must be quantitated separately with individual desorption efficiency corrections, and then the resulting amounts are summed to determine the total amount of Dipropylene glycol methyl ether (Dipropilen glikol metil eter). This procedure is necessary for any method using charcoal collection and carbon disulfide desorption because the relative proportion of isomers in Dipropylene glycol methyl ether (Dipropilen glikol metil eter) can vary by lot and manufacturer.Using this desorption solvent, the desorption efficiencies of all the isomers of Dipropylene glycol methyl ether (Dipropilen glikol metil eter) were found to be essentially identical at approximately 100%, thus peak summations can be done.The desorption efficiencies from dry charcoal ranged from 76-93% for the isomers at a loading of 6.0 mg of Dipropylene glycol methyl ether (Dipropilen glikol metil eter).In the review presented in the previously mentioned NEG/NIOSH document, it was concluded that Dipropylene glycol methyl ether (Dipropilen glikol metil eter) seems to lack reproductive toxicity, unlike some other chemically similar compounds.At very high air concentrations, Dipropylene glycol methyl ether (Dipropilen glikol metil eter) causes narcosis in animals. It is expected that severe exposure would produce similar effects in humans, but high concentrations are disagreeable and not tolerated.Dipropylene glycol methyl ether (Dipropilen glikol metil eter) at 300 ppm caused eye and nasal irritation to humans.ACGIH has established a TLV-TWA of 100 ppm and a TLV-STEL of 150 ppm for Dipropylene glycol methyl ether (Dipropilen glikol metil eter).Dipropylene glycol methyl ether (Dipropilen glikol metil eter) is used as a solvent for paints, lacquers, resins, dyes, oil/greases, cleaners and cellulose and as a heat-transfer agent. It is frequently used as a substitute for the more toxic DEGME (diethylene glycol methyl ether).Dipropylene glycol methyl ether (Dipropilen glikol metil eter) is a mixture of structural isomers. Also, each isomer has two asymmetrical carbon atoms, thus configurational isomers can exist. The numbers in parentheses are approximate percentages by weight of each isomer found in the Dipropylene glycol methyl ether (Dipropilen glikol metil eter) used in this evaluation. The abbreviations in the brackets are used in chromatograms in this method.Dipropylene glycol methyl ether (Dipropilen glikol metil eter) is a glycol ether based on propylene oxide and methanol. It is a speciality solvent having a bi-functional nature (ether-alcohol). It is a clear liquid with an ether-like odour. Dipropylene glycol methyl ether (Dipropilen glikol metil eter) is not flammable, but a combustible liquid with a flashpoint of 1670 F/750C. Typically, the concentration of Dipropylene glycol methyl ether (Dipropilen glikol metil eter) is 99%; 2-Methoxypropanol-1 can be present as an impurity at max. 0.1%. Dipropylene glycol methyl ether (Dipropilen glikol metil eter) is not classified as a carcinogen or mutagen; it is not expected to cause cancer in humans, nor does it impair fertility or damage the developing fetus. Dipropylene glycol methyl ether (Dipropilen glikol metil eter) is transported by tank truck, rail car and vessel, primarily in bulk quantities, but also as a packed product. It is not classified as hazardous for transport under transport regulations.Dipropylene glycol methyl ether (Dipropilen glikol metil eter) at any exposure concentration in either male or female rats or rabbits. The highest concentration tested (200 ppm) was approximately 40% of a saturated Dipropylene glycol methyl ether (Dipropilen glikol metil eter) atmosphere, Based on the low vapor pressure of Dipropylene glycol methyl ether (Dipropilen glikol metil eter), and results in this 13-week study, Dipropylene glycol methyl ether (Dipropilen glikol metil eter) appears to have a low subchronic vapor inhalation toxicity hazard.Dipropylene glycol methyl ether (Dipropilen glikol metil eter) may react violently with strong oxidizing agents. May generate flammable and/or toxic gases with alkali metals, nitrides, and other strong reducing agents. May initiate the polymerization of isocyanates and epoxides.The invention discloses a method for preparing Dipropylene glycol methyl ether (Dipropilen glikol metil eter). The method for preparing the Dipropylene glycol methyl ether (Dipropilen glikol metil eter) is characterized by comprising the following steps of taking tower bottoms left after propylene glycol methyl ether is extracted as raw materials, performing a ring-opening addition reaction on the raw materials and epoxypropane in the presence of a strongly basic catalyst, recovering excessive 2-methoxy-1-propyl alcohol in the synthetic products by virtue of rectification and then separating to obtain the product Dipropylene glycol methyl ether (Dipropilen glikol metil eter). The method for preparing the Dipropylene glycol methyl ether (Dipropilen glikol metil eter) has the advantages that as15-25% of Dipropylene glycol methyl ether (Dipropilen glikol metil eter) continues reacting with the epoxypropane to generate tripropylene glycol methyl ether which is higher in boiling point in the process of synthesizing the Dipropylene glycol methyl ether (Dipropilen glikol metil eter) by reacting the tower bottoms and the epoxypropane, enough output of the tripropylene glycol methyl ether is guaranteed by use of the synthesis method, and the tripropylene glycol methyl ether is capable of continuing dissolving catalysts such as sodium methylate and sodium hydroxide so that the sodium methylate can be prevented from being decomposed to generate methanol as being heated under the circumstance of a relatively high concentration, and therefore, the potential hazard that the methanol is possible to be in an explosion range after being mixed with air and explodes under high heat can be avoided.The present invention relates to a kind of method of preparing Dipropylene glycol methyl ether (Dipropilen glikol metil eter), belong to organic solvent preparation field.1. a method of preparing Dipropylene glycol methyl ether (Dipropilen glikol metil eter), it is characterized in that: the tower bottoms having extracted after propylene glycol monomethyl ether of take is raw material, under the effect of strong alkali catalyst, carry out opening with propylene oxide, by rectifying, reclaim out after 2-methoxy-1-propanol excessive in synthetic product, then separation obtains product Dipropylene glycol methyl ether (Dipropilen glikol metil eter).
