Abstract: 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.

Abstract: In a process for the production of para-xylene, an aromatic feedstock comprising toluene and/or benzene is reacted with methanol under alkylation conditions in a reactor in the presence of a fluidized bed of solid catalyst particles to produce a vapor phase effluent comprising para-xylene, water, unreacted toluene and/or benzene and solid catalyst fines. The vapor phase effluent is contacted with a liquid hydrocarbon quench stream under conditions to condense a minor portion of the vapor phase effluent and produce a condensate which contains at least some of the catalyst fines and which is substantially free of an aqueous phase. The condensate containing said catalyst fines is then separated from the remainder of the vapor phase effluent.

Abstract: This disclosure is directed to an integrated method for making synthetic hydrocarbon fluids, plasticizers and polar synthetic lubricant base stocks from a renewable feedstock. More particularly, the disclosure is directed to a metathesis reaction of natural oil or its derivative ester and ethylene in the presence of an effective amount of a metathesis catalyst to form linear alpha-olefins, internal olefins and reduced chain length triglycerides. The linear alpha-olefins and/or internal olefins are polymerized to produce synthetic hydrocarbon fluids in the presence of a suitable catalyst. The reduced chain length triglycerides are converted into polar synthetic lubricant base stocks or plasticizers by hydrogenation, isomerization, followed by hydrogenations, or by hydroisomerization processes. Alternatively, the reduced chain length triglycerides can also be epoxidized to form epoxidized triglyceride plasticizers, optionally followed by carbonation, to form carbonated triglyceride plasticizers.

Abstract: In a process for the production of para-xylene, methanol is preheated to a first temperature, an aromatic feedstock comprising toluene and/or benzene is preheated to a second temperature and the preheated methanol and aromatic feedstocks are fed to a reactor at a first methanol to aromatic feedstock molar ratio. The preheated aromatic feedstock is contacted with the preheated methanol under alkylation conditions in the reactor in the presence of a catalyst so that the methanol reacts with the aromatic feedstock to produce an effluent comprising para-xylene. During the reaction, a temperature is measured within the reactor and is compared with a predetermined optimal temperature. The methanol to aromatic feedstock molar ratio is then adjusted in a manner to reduce any difference between the measured and predetermined optimal temperatures in the reactor.

Abstract: In a process for oxidizing alkylaromatic compounds to the corresponding hydroperoxide, an alkylaromatic compound of general formula (I): in which R1 and R2 each independently represents an alkyl group having from 1 to 4 carbon atoms, provided that R1 and R2 may be joined to form a cyclic group having from 4 to 10 carbon atoms, said cyclic group being optionally substituted, and R3 represents hydrogen, one or more alkyl groups having from 1 to 4 carbon atoms or a cyclohexyl group, with oxygen in the presence of an added catalyst comprising tert-butyl hydroperoxide and in the absence of any other catalyst, to produce a hydroperoxide of general formula (II): in which R1, R2 and R3 have the same meaning as in formula (I). The hydroperoxide may then be converted into a phenol and a ketone of the general formula R1COCH2R2 (III), in which R1 and R2 have the same meaning as in formula (I).
