A process for producing tert-butylphenyl diphenyl phosphate which is stable at low temperature by a process wherein phenol is butylated to produce tert-butylphenol which is isomerized to produce mixed meta and para isomers thereof, and which thereafter is alkylated with isobutylene to
4414161 Process for producing low temperature stable tert-butylphenyl diphenyl phosphate November 8, 1983
A process for producing tert-butylphenyl diphenyl phosphate which is stable at low temperature by a process wherein phenol is butylated to produce tert-butylphenol which is isomerized to produce mixed meta and para isomers thereof, and which thereafter is alkylated with isobutylene to
4403056 Carbonate esters, carbonate ester compositions, and plasticized compositions September 6, 1983
A carbonate ester of the formula: ##STR1## where n is an integer of from 0 to 4 and m is an integer of from 8 to 14 and carbonate ester compositions containing at least one of such compounds are disclosed. These compounds or compositions can be added to vinyl chloride polymer com
4378320 Meta-tertiary-butylphenyl diphenyl phosphate March 29, 1983
Tertiary-butylphenyl diphenyl phosphate esters in which the nominal molar ratio of tertiary-butyl radicals to phenyl radicals ranges from about 1:5 to about 1:2, the meta-tertiary-butylphenyl content ranges from about 25% to about 100 % and the ortho-tertiary-butylphenyl content is less
4351780 Process for preparing isopropylphenyl/phenyl phosphate September 28, 1982
Monoisopropylphenyl/phenyl phosphate containing mixtures are prepared by, (1) alkylating phenol with propylene to C.sub.3 /.phi. ratio of less than 0.30 with a p-toluene sulfonic acid catalyst, (2) removing unreacted phenol as distillate to yield a distilland having a C.sub.3 /.phi. rati
4280945 Vinyl chloride compositions plasticized with meta-tertiary-butylphenyl diphenyl phosphate July 28, 1981
Tertiary-butylphenyl diphenyl phosphate esters in which the nominal molar ratio of tertiary-butyl radicals to phenyl radicals ranges from about 1:5 to about 1:2, the meta-tertiary-butylphenyl content ranges from about 25% to about 100% and the ortho-tertiary-butylphenyl content is less t
4163767 Polyalkylene glycol alkyl polyphosphites August 7, 1979
A polyphosphorous mixed phosphite-phosphonate polymer flame retardant having an OH number less than one and containing both alkyl phosphite and haloalkyl phosphonate linkages.
4103096 Preparation of meta-alkylphenols July 25, 1978
Meta-alkylphenols are prepared by the isomerization of nonmeta-alkylphenols in the presence of trifluoromethane sulfonic acid. Ortho-isomer-containing alkylphenols are isomerized to increase their meta-isomer content and reduce their ortho-isomer content.
3993692 Methane sulfonyl chloride and process of preparation November 23, 1976
A continuous process for preparing methane sulfonyl chloride by the reaction of methyl mercaptan with chlorine in the presence of an aqueous bath of hydrogen chloride at an elevated temperature.
3986990 Flame retardant polyurethane foam containing polyalkylene glycol alkyl poly-phosphites October 19, 1976
Polyalkylene glycol alkyl polyphosphites characterized by low OH numbers and relatively little glycol in the side chain are prepared by reacting a tertiary phosphite with a polyalkylene glycol in a molar ratio of from about 1 to 1.5 moles of phosphite per mole of glycol. These polyphosph
3931367 Color improvement of phosphate esters January 6, 1976
A method for decolorizing and stabilizing alkylphenyl esters of phosphoric acid which comprises contacting the esters with an effective amount of a stannous fatty acid salt for a sufficient length of time to decolorize and stabilize the esters against subsequent color formation.
3931366 Color improvement of phosphate esters January 6, 1976
A method for decolorizing and stabilizing alkylphenyl esters of phosphoric acid which comprises the in situ addition of an effective amount of PCl.sub.3 to the POCL.sub.3 reacted with an alkyl phenol so as to produce a decolorized and stabilized phosphate ester.
3931365 Color improvement of phosphate esters January 6, 1976
