    • Processes for the preparation of 3-alkoxyalkanols useful as solvents for coating materials, photoresists, or the like.
      Specifcally,

      (1) a process which comprises reacting an α,β-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 α,β-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.
    • 用作制备用作涂料,光致抗蚀剂等的溶剂的3-烷氧基烷醇的方法。 具体地,(1)一种方法,其包括在酸性催化剂存在下使α,β-不饱和醛与醇反应,并使所得产物依次水解和氢化; (2)一种方法,其包括使α,β-不饱和醛与醇反应获得的反应混合物与包含相应的1,1,3-三烷氧基烷烃和3-烷氧基烷烃的物质同时进行水解和氢化; (3)一种方法,其包括通过蒸馏作为其与水的共沸混合物从由与丙烯或异丁烯氧化制备的含酸丙烯醛或甲基丙烯醛反应获得的反应溶液中回收3-烷氧基烷烃,并将其氢化 将回收的3-烷氧基亚油酸转化为相应的3-烷氧基烷醇; 和(4)一种方法,其包括使由丙烯或异丁烯氧化产生的气体与醇接触,进行气体与醇的反应,形成相应的1,1,3-三烷氧基烷烃,并使其 水解和氢化。
