Provided are a novel halogenoacetoxyadamantane derivative which is useful as a modifying agent for a resin for a photoresist and a dry etching resistance-improving agent in the photolithography field, agricultural and medical intermediates and a compound for other various industrial products and a process for producing the same. To be specific, provided are a halogenoacetoxyadamantane derivative having a halogenoacetoxy group in an adamantane skeleton and a process for producing a halogenoacetoxyadamantane derivative, comprising the step of reacting a hydroxyl group of an adamantane skeleton with halogenoacetic halide or reacting the above hydroxyl group with a lithiation agent to derive it into a lithiumoxy group and then reacting halogenoacetic halide to introduce a halogenoacetoxy group.

Processes for the preparation of 3-alkoxyalkanols useful as solvents for coating materials, photoresists, or the like. Specifically, (1) a process which comprises reacting an &agr;,&bgr;-unsaturated aldehyde with an alcohol in the presence of an acidic catalyst and subjecting the obtained product to hydrolysis and hydrogenation successively; (2) a process which comprises subjecting a reaction mixture obtained by the reaction of an &agr;,&bgr;-unsaturated aldehyde with an alcohol and comprising the corresponding 1,1,3-trialkoxyalkane and 3-alkoxyalkanal to hydrolysis and hydrogenation at the same time; (3) a process which comprises recovering a 3-alkoxyalkanal through distillation as an azeotropic mixture thereof with water from a reaction solution obtained by the reaction of an alcohol with acid-containing acrolein or methacrolein prepared by the oxidation of propylene or isobutylene, and hydrogenating the recovered 3-alkoxyalkanal into the corresponding 3-alkoxyalkanol; and (4) a process which comprises bringing a gas produced by the oxidation of propylene or isobutylene into contact with an alcohol, conducting the reaction of the gas with the alcohol to form the corresponding 1,1,3-trialkoxyalkane, and subjecting it to hydrolysis and hydrogenation.
