Abstract: The invention relates to a method for production of polyvalent alcohols with low acetal content by catalytic hydrogenation of methylolalkanals of general formula (I), where R 1 and R 2 independently = a further methylol or C 1 - 22 alkyl group or C 6 - C 33 aryl or aralkyl group in the liquid phase on a hydrogenation catalyst, characterised in that at least one tertiary amine, inorganic base or inorganic or organic acid is added to the hydrogenation feed to adjust the pH value of the hydrogenation product to 7.0 to 9.0.

Abstract translation: 一种用于在具有由通式（I）的羟甲基链烷的催化氢化的低乙缩醛的制备多元醇的方法，其中R ^{1 和R 2 彼此独立地，进一步的羟甲基或烷基基团的 具有1至22个碳原子或至少加入叔胺，无机碱或无机酸或有机酸的具有在氢化催化剂6至33个碳原子，在液相中的芳基或芳烷基，其特征在于 氢化调节至pH 7.0至9.0的氢化。}

Abstract: The invention relates to a process for separating off maleic anhydride from a gas stream comprising maleic anhydride, in which a) the gas stream comprising maleic anhydride is brought into contact with a liquid absorbent phase comprising at least one high-boiling inert absorption medium for maleic anhydride and b) maleic anhydride is separated off from the resulting liquid absorbate phase by stripping with a hydrogen-comprising gas as stripping medium in a column, wherein the stripping medium is fed in at two points on the column which are at least one theoretical plate apart.

Abstract: The present invention relates to a process for purifying 1,4-butynediol, which comprises compressing 1,4-butynediol to from 50 to 1500 bar, depressurizing it, waiting for phase separation to occur after depressurization and separating off the bottom phase, and a process for the hydrogenation of 1,4-butynediol to 1,4-butenediol and 1,4-butanediol using the purified 1,4-butynediol.
