摘要： A process for the production of a dialkyl carbonate and a diol, such as dimethyl carbonate and ethylene glycol, by reacting a feed containing a cyclic carbonate, a hydroxy alkyl carbonate and an aliphatic monohydric alcohol in the presence of a transesterification catalyst is described. In another aspect, a process is described which is particularly useful for producing unsymmetric dialkyl carbonates, such as ethyl methyl carbonate.

摘要： An integrated process for the production of a dialkyl carbonate and a diol from an alkylene oxide, carbon dioxide and an aliphatic monohydric alcohol is described in which an alkylene oxide is first reacted with carbon dioxide in the presence of a halogen-free carbonation catalyst to provide a corresponding cyclic carbonate and the cyclic carbonate is then reacted with an aliphatic monohydric alcohol in the presence of the carbonation catalyst and/or a transesterification catalyst and recycling the carbonation catalyst to provide a corresponding dialkyl carbonate and diol, wherein the dialkyl carbonate product exhibits a halogen concentration of about 5 ppm or less.

摘要： The novel synthetic polyethylene fluids of the present invention are characterized by high viscosity indices (about 94-151 VI), low pour points (about -60 to -10.degree. C.), and a kinematic viscosity of about 6 to 28 cSt KV at 100.degree. C. The product compositions comprise polymers having a molecular weight of from about 300 to about 30,000 and a branching index of 151 to 586 branches per 1000 CH.sub.2 groups, or BI=0.18-0.40. A process for preparing such novel synthetic polyethylene fluids comprises polymerizing ethylene in the presence of a catalyst system, said catalyst system comprising [A] and [B], wherein [A] is a catalyst having the formula MX.sub.5 and [B] is a co-catalyst having the formula R.sub.n AlX.sub.3-n where M is a Group VB, VIB, or VIII transition metal; X is a halogen anion; R is a C.sub.1 -C.sub.20 alkyl group; and n is 1-2.
