    摘要： A process for preparing alkyl glyceryl sulfonate includes fractionally distilling an alkyl glyceryl epoxide mixture to afford alkyl glyceryl epoxide of formula IV: where R is a C4-12 alkyl, in at least about 98.0% purity by weight with respect to epoxidized compounds, the epoxidized compounds comprising the alkyl glyceryl epoxide of formula IV, dimer alkyl glyceryl epoxide of formula V, and trimer alkyl glyceryl epoxide of formula VI: where R is a C4-12 alkyl; and reacting the at least about 98.0% alkyl glyceryl epoxide of formula IV with a mixture of an alkali bisulfite and an alkali sulfite in a sulfonation reaction at a temperature, to afford the alkyl glyceryl sulfonate of formula I: where R is a C4-12 alkyl and M is an alkali metal.

    摘要： A semi-continuous process for the manufacture of acetals of chloroacetaldehyde is described. In a preferred embodiment of the invention, chloroacetaldehyde dimethyl acetal is prepared by introducing chlorine and vinyl acetate through separate inlets into the upper opening of a cooled vertical packed column to form an intermediate product. The intermediate flows through the column, and optionally a static mixer, into a cooled batch reactor precharged with an excess of methanol to form the crude acetal product. Isolation and purification of the product is accomplished by known batch-type procedures.

    摘要： Quaternary ammonium monomers and monomers copolymerizable therewith are reacted in the presence of anionic polymers to directly form a dry coacervate by a process which comprises forming a solution comprising the monomer(s), the anionic polymer, solvent(s) and a free-radical initiator and simultaneously polymerizing and drying the solution at a temperature above the boiling point of the solvent.
