Production
1,2,3-Trichloropropane can be produced via the chlorination of propylene. Other reported methods for producing 1,2,3-trichloropropane include the addition of chlorine to allyl chloride, reaction of thionyl chloride with glycerol, and the reaction of phosphorus pentachloride with either 1,3- or 2,3-dichloropropanol. TCP also may be produced as a byproduct of processes primarily used to produce chemicals such as dichloropropene (a soil fumigant), propylene chlorohydrin, propylene oxide, dichlorohydrin, and glycerol.
Uses
Historically, TCP has been used as a paint or varnish remover, a cleaning and degreasing agent, and was an impurity in certain pesticides. It is also used as a chemical intermediate in the process of making chemicals, such as hexafluoropropylene and polysulfides, and as an industrial solvent.
Solvent
1,2,3-TCP had purportedly been used in the past as a solvent for paint and varnish removal, as a cleaning and degreasing agent, and as a cleaning and maintenance solvent. No current information is available to indicate that it continues to be used for these purposes.
Soil fumigants
Pre-1980s, agricultural use of chloropropane-containing soil fumigants for use as pesticides and nematicides was prevalent in the United States. Some soil fumigants, which contained a mixture of primarily 1,3-dichloropropene and 1,2-dichloropropane, and in which 1,2,3-TCP was a minor component, e.g., trade name of D-D, were marketed for the cultivation of various crops including citrus fruits, pineapples, soy beans, cotton, tomatoes,and potatoes. D-D was first marketed in 1943, but is no longer available in the United States, and has been replaced with Telone II, which was first available in 1956. Telone II reportedly contains as much as 99 percent 1,3-dichloropropene and up to 0.17 percent by weight 1,2,3-TCP (Zebarth et al., 1998). Before 1978, approximately 55 million pounds/year of 1,3-dichloropropene were produced annually in the United States, and approximately 20 million pounds/year of 1,2-dichloropropane and 1,2,3-TCP were produced as by-products in the production of 1,3-dichloropropene. Over 2 million pounds of pesticides containing 1,3-dichloropropene were used in California alone in 1978. Telone II is still used for vegetables, field crops, fruit and nut trees, grapes, nursery crops, and cotton.
Aircraft fuel tank sealers
Another documented use of 1,2,3-TCP was as a “branching” or curing agent in polysulfide polymers (Kirk Othmer Chemical Encyclopedia, 2001). Polysulfide polymers have been used as the “standard sealant for virtually all aircraft fuel tanks and bodies” since the 1950s. Also, “one of the first large-scale applications of the liquid polysulfides was as a binder for rocket fuel,” from 1946 until 1958. Summary tables published by Kirk Othmer (2001) list the properties of a number of Morton Thiokol LP series of polysulfide polymer-based sealers, with concentrations of the branching agent (1,2,3-TCP) ranging from 0.5 to 2.0 percent. Liquid polysulfide polymers are used mainly as sealants in manufacturing applications, including applications related to double-paned windows, boat hulls and decks, printing rolls, integral aircraft fuel tanks, and aircraft bodies.
Chemical intermediates
By the early 1980s, approximately 95 percent of chloropropanes were being used as chemical intermediates. Chemical intermediates are industrial chemicals that are used as the starting point to produce other chemicals. 1,2,3-TCP is currently used as an intermediate in the production of polysulfone liquid polymers, the synthesis of hexafluoropropylene, and as a cross-linking agent in the synthesis of polysulfides. Polysulfone liquid polymers are used in the following industries: aerospace, automotive,consumer goods, electrical and electronic, health care, and in industrial equipment, such as compressor and pump valve components. Hexafluoropropylene is a fluorointermediate that is a key building block required to produce Teflon fluoropolymers; it has applications in the agrochemical, electronics, dyes/pigments, pharmaceutical, and specialty polymermarkets. Polysulfides are used as catalyst sulfidation agents and in the formulation of lubricant additives created for use in high-pressure environments or applications.
Manufacturers
1,2,3-TCP is manufactured as a stand-alone product in the United States. It also is produced in significant quantities as an unwanted by-product of the production of other chlorinated compounds such as epichlorohydrin, and is used internally by manufacturers as an intermediate in the production of other chemicals such as polysulfone and epoxy resins.
What is TCP?
– TCP is a chlorinated hydrocarbon with high chemical stability (Samin and Janssen 2012).
– Synonyms include allyl trichloride, glycerol trichlorohydrin and trichlorohydrin (OSHA 2013).
– TCP is exclusively a man-made chemical, typically found at industrial or hazardous waste sites (Dombeck and Borg 2005; ATSDR 1992).
– TCP has been used as an industrial solvent and as a cleaning and degreasing agent; it has been found as an impurity resulting from the production of soil fumigants (DHHS 2011; HSDB 2009).
– TCP is currently used as a chemical intermediate in the production of other chemicals (including polysulfone liquid polymers and dichloropropene), and in the synthesis of hexafluoropropylene. In addition, it is used as a crosslinking agent in the production of polysulfides (DHHS 2011; HSDB 2009).
What are the environmental impacts of TCP?
– TCP is not likely to sorb to soil based on its low soil organic carbonwater partition coefficient; therefore, it is likely to either leach from soil into groundwater or evaporate from soil surfaces (ATSDR 1992; HSDB 2009).
