Surfaces contaminated with chloromethylmethyl ether and bis-chloromethyl ether may be decontaminated by treating them with an aqueous solution of a basic organic amine, for example a tertiary amine, a nonionic surfactant and an alkali-metal hydroxide.

Method for rapid decomposition of methyl chloromethyl and

An improved process for chloromethylating an aromatic material comprising introducing in a first closed container the aromatic polymeric material, catalyst for the chloromethylation reaction, and chloromethyl methyl ether in sufficient excess to insure completion of the chloromethylation reaction, and then performing the following series of steps:

Process for preparing chloromethylated aromatic materials

Esters of 4-substituted 2-methyleneglutaric acids are prepared by reacting an ester of acrylic acid with an ester of an .alpha.-substituted acrylic acid, such as an ester of methacrylic acid, in the presence of a tertiary organic phosphine, an organic phosphorus triamide, an organic phosphonous diamide, or an organic phosphinous amide.

Esters of 4-substituted 2-methyleneglutaric acids and method for

Amphoteric resins are prepared by the Strecker synthesis of crosslinked vinylcarbonyl polymers. The crosslinked vinylcarbonyl polymer such as, for example, polyacrolein is reacted with an amine component such as ammonia and an inorganic cyanide to obtain after hydrolysis resins having good weak base and weak acid exchange capacities. The amphoteric nature and higher capacities make them highly suitable for the removal of sulfur oxides from waste streams.
