Abstract: The invention is directed toward novel high molecular weight and high purity mPEG alcohol compositions as well as a process for obtaining said compositions by removing PEG diols from the mPEG alcohol after polymerization is complete.

Abstract: Certain phenyl and N-heterocyclic phosphorothioates and phosphonothioates and phosphates are prepared by the reaction of an appropriate alkali metal or alkaline earth metal --0-phenyl or N-heterocyclic compound with an appropriate phosphorochloridate, phosphorochloridothioate, phosphonochloridate or phosphonochloridothioate under alkaline conditions in the presence of a tertiary amine catalyst and a nonionic surfactant having an HLB Value of from about 1 to about 20, preferably about 5 to 15, in a two-phase system, one phase being primarily the phosphorate or phosphonate reactant and a complex thereof with the tertiary amine catalyst and the other phase being an aqueous reaction medium comprising water, a buffer system, and the alkali metal or alkaline earth metal-O-phenyl or --O-N-heterocyclic compound, in the substantial or complete absence of an organic solvent the aqueous reaction medium being maintained at pH about 10 to 12 by the buffer system.

Abstract: Certain phenyl and N-heterocyclic phosphorothioates and phosphates are prepared by the reaction of an appropriate alkali metal or alkaline earth metal -O-phenyl or N-heterocyclic compound with an appropriate phosphorochloridate or phosphorochloridothioate under alkaline conditions in a liquid reaction medium and in the presence of a tertiary amine catalyst and a nonionic surfactant having a HLB Value of from about 2.5 to about 20 or more.

Abstract: A 1,1-diphenylethane and an aromatic compound such as benzene are reacted in the presence of a Friedel-Craft's catalyst to provide a compound having two 1,1-diaromatic substituted ethane groups, dehydrogenation provides a bis(1-phenylethenyl)aromatic compound.

Abstract: A process for the removal of oxazole from acrylonitrile by contacting oxazole-containing acrylonitrile with a substantially dry cation exchange resin. The process exhibits the advantage of up to 40 percent or greater increase in the oxazole removal capacity than a corresponding process employing a water-wet cation exchange resin.
