摘要:
Provided is a process for making non-phthalate plasticizers, by acylating an aromatic compound with a succinic anhydride to form a keto-acid, and then esterifying the keto-acid with C4-C13 OXO-alcohols to form a plasticizer compound. The aromatic rings of the aromatic compound may also be optionally hydrogenated.
摘要:
A process for making non-phthalate, 1,2-phenylene oxo-diester plasticizers for polymer compositions, by selectively hydrogenating naphthalene to form a partially hydrogenated naphthalene, oxygenating said partially hydrogenated naphthalene to form phenylene diacids, and esterifying said phenylene diacids with oxo-alcohols to form 1,2-phenylene oxo-diesters. Also a process for making phenylene oxo-diester plasticizers by selectively brominating xylenes to form bisbromomethylbenzene, catalytic carboalkoxylation of the bromo-compound to form phenylene diacetate, followed by transesterification to form the phenylene oxo-diester.
摘要:
Mono- or diester plasticizers of the formula: wherein A is either —OC(O)R′ or ═O, and X is either —COC(O)R or —C(O)OR, and R and R′ are C3 to C13 alkyl, which are the same or different, formed from cyclohexylbenzene and processes of making them.

摘要:
Provided are compositions, processes for making, and processes for using neoalkyl polyol esters and triglycerides as plasticizers. In one form, a neoalkylester triglyceride plasticizers can be produced by (i) drying a polyol feedstream; (ii) contacting in a reactor the dried polyol feedstream with a neoacid feedstream under effective temperature, pressure and time to form a neoalkylester plasticizer effluent stream, and (iii) purifying the neoalkylester plasticizer effluent stream to remove unreacted polyol and unreacted neoacid to form a neoalkylester plasticizer. Such plasticizers can be phthalate-free and provide outstanding properties including a suitable melting or pour point, glass transition temperature, low volatility, increased compatibility, increased hydrolytic stability, and excellent low temperature properties in a range of polymeric resins.

摘要:
Provided are compositions, processes for making, and processes for using triglycerides as plasticizers. Triglyceride plasticizers can be produced by recovery of linear or branched C4 to C10 aldehydes from a hydroformylation product, oxidation to the acid with oxygen and/or air, recovery of the resulting acid, and esterification with glycerol, wherein the total carbon number of the triester groups is from 20 to 25 for greater than or equal to 45 wt % of the plasticizer. Such plasticizers can be phthalate-free and provide outstanding properties including a suitable melting or glass transition or pour point, low volatility, increased compatibility, and excellent low temperature properties in a range of polymeric resins.
