Phosphate cresyl diphenyl

Phosphites. The phosphates, second only to phthalates in production volume, are favored for flame resistance and low volatility. Tricresyl phosphate (mixed meta and para isomers) is the most popular it is used in polyvinyl chloride and in nitrocellulose lacquers. Resins plasticized with tricresyl phosphate are deficient in low-temperature flexibility. Diphenyl cresyl phosphate and triphenyl phosphate are other examples, the former for polyvinyl chloride, the latter for cellulose acetate. Diphenyl-2-ethylhexylphosphate is preferred to tricresyl phosphate in polyvinyl chloride where its low toxicity and improved low-temperature flexibility are required. Tn(2-elliylliexyl)-phosphale is outstanding among phosphates used in polyvinyl chloride with respect to low-temperature flexibility in flame- and oil resistance, however, it is inferior to tricresyl phosphate. Tri(butoxvethyl)phosphate finds some use in synthetic rubber. 

Patent literature reports also on halogen-free composition for PS foams, using phosphorus compound, such as RP, triphenyl phosphate, diphenyl cresyl phosphate, APP or diphenyl phosphate, and metal hydroxide such as magnesium or aluminum hydroxide.88 It is reported that PS foams containing a mixture of EG (6-10 wt%), inorganic compound (5-10 wt%) and RP, triphenyl phosphate (TPP) or 9,10-dihydro-9-oxa-10-phosphaphenanthrene 10-oxide (DOP)), and chalk compounds (5-10 wt%)89 or containing EG and phosphorus compounds such as RP, triphenylphosphate diphenyl cresyl phosphate, APP, melamine phosphate, resorcinol diphenyl phosphate, and dimethyl methylphosphonate in suitable amounts90 fulfills DIN 4102-B2 requirements. 

Triphenyl phosphate, diphenyl-cresyl phosphate, tricresyl phosphate and mixed (2-propyl-phenyl)-phenyl phosphates belong to this class of compounds. They are manufactured by reacting phosphorus(V) oxychloride with a slight excess of the appropriate phenols or phenol mixtures in the presence of catalysts (magnesium or potassium salts) at temperatures above 140°C ...

Desmocoll 176 is compatible with such plasticizers as benzyl butyl phthalate, diphenyl cresyl phosphate and trichlorethyl phosphate. It has slight or no compatibility with dibutyl phthalate, dioctyl phthalate, triphenyl phosphate, tricresyl phosphate, dibutyl adipate, benzyl octyl adipate, phenyl and cresyl alkyl sulphonates.

Today, TCP made from o-cresol-free feedstock is still used in vinyl composites for clear agricultural film applications (greenhouses) in Asia. Cresyl diphenyl phosphate is widely used in Europe and Asia because of its high efficiency and very low cost. For most U.S. vinyl markets, however, it is not considered, because of lingering toxicity concerns. However, modern cresyl phosphates, largely free of the o-cresyl isomer, are not serious neurotoxins, and are seen in applications as flame-retarded, low-foaming hydraulic fluids in power generating stations.

The volume leaders among fire retardants with 35 million pounds were the three phosphate plasticizers for PVC tricresyl phosphate, cresyl diphenyl phosphate and triphenyl phosphate. The remaining 6 million pounds were made up of octyl diphenyl phosphate, tributyl phosphate, tri(dibromopropyl) phosphate, tri(dichloropropyl) phosphate and tri-(chloroethyl) phosphate. Polymeric phosphorus and phosphorus halogen-containing additives are used in concentrations of 3-25 p.p.h. in polyesters, flexible and rigid polyurethane foam, and phenolics.
