Title: Production of 1,1-bis (chloromethyl)-1 hydroxymethylpropane and 1-mono(chloromethyl)-1,1-bis (hydroxymethyl) propane
Inventor: ITO NAOKAZU
IPC: C07C31/42
Filed: 1996-11-14
Abstract: PROBLEM TO BE SOLVED: To obtain the subject compound in one step and high yield by remarkably decreasing the amount of a lower aliphatic carboxylic acid compared with conventional process. SOLUTION: The objective compound is produced by reacting trimethylolpropane(TMP) with hydrogen chloride gas in the presence of 0.01-0.2mol of a 2-5C lower aliphatic carboxylic acid (preferably acetic acid or propionic acid) based on 1.0mol of TMP. The reaction is preferably carried out while distilling out produced water from the reaction system. As necessary, an organic compound capable of forming an azeotropic mixture with water except for alcohols and esters (e.g. benzene, toluene or xylene) can be used as the reaction solvent. The amount of hydrogen chloride gas supplied to the system is preferably 1.0-10.0mol based on 1.0mol of TMP. The objective compound is useful as an intermediate raw material for a compound having an oxetan ring enabling ring-opening polymerization.
