  The problem to be solved is to provide a process for producing a polyoxymethylene copolymer in a molding machine with a reduced generation of formaldehyde gas. In a process for continuously producing a polyoxymethylene copolymer comprising a step of melt-kneading a crude polyoxymethylene copolymer at a temperature not lower than the melting point thereof, devolatilizing under reduced pressure the formaldehyde gas generated as a decomposition product, subsequently mixing a formaldehyde scavenger containing a hydrazide compound (A) while keeping the copolymer in a molten state and immediately pelletizing the mixture, a dispersed solution obtained by slurry-dispersing said (A) in a diluent (B) having a melting point lower than temperature (Ta) which is the lower of the melting point and the decomposition temperature of (A), within a temperature range not lower than the melting point of (B) and lower than (Ta) is used as the formaldehyde scavenger.

  要解决的问题是提供一种在成型机中生产聚甲醛共聚物的工艺，该工艺可减少甲醛气体的产生。在一种连续生产聚甲醛共聚物的工艺中，包括以下步骤：在不低于熔点的温度下对粗聚甲醛共聚物进行熔融捏合，在减压下使作为分解产物产生的甲醛气体脱溶，随后在保持共聚物处于熔融状态的同时混合含有酰肼化合物（A）的甲醛清除剂，并立即对混合物进行造粒、将所述 (A) 在稀释剂 (B) 中进行浆状分散而得到的分散溶液用作甲醛清除剂，稀释剂 (B) 的熔点低于 (A) 的熔点和分解温度中较低的温度 (Ta)，温度范围不低于 (B) 的熔点且低于 (Ta)。

  Allyl alcohol production processes are generally described herein. One or more of the processes generally include contacting a propylene oxide stream with an isomerization catalyst under isomerization conditions sufficient to form an isomerization product stream including allyl alcohol, wherein the propylene oxide stream includes a total impurity concentration of at least 100 ppm. One or more of the processes generally includes purging at least a portion of a stream from one or more separation unit(s).
