Method for the preparation of aliphatic chloroformates

A method for preparing an aliphatic chloroformate comprising, introducing a mixture of at least one aliphatic hydroxyl compound, phosgene, at least one solvent, and optionally at least one organic base into a flow reactor to obtain a unidirectional flowing reaction mixture. The at least one aliphatic hydroxyl compound comprises at least one aliphatic hydroxyl group. The unidirectional flowing reaction mixture is maintained at a temperature between about 0° C. and about 60° C. to produce a single product stream comprising an aliphatic chloroformate.

Oxyformamidates

Compounds of the formula STR1 WHEREIN A is a linking group, X is an O--CO-- or --SO2 -- group and n is at least 2, are prepared from the corresponding N',N'-disubstituted hydrazides by quaternization and treatment with alkali or reaction with an alkylene epoxide or from the corresponding compound wherein n = 1 and A is a polymerizable group by polymerization. The compounds are unstable to heat and may be used as cross-linking agents for polymers or as chain-extending agents, bonding agents or adhesives.
