CN105061203A 一种季戊四醇酯的制备方法 无效 - 驳回

一种季戊四醇酯的制备方法
摘要：
本申请属于化工技术领域，尤其涉及一种季戊四醇酯的制备方法。本申请提供的季戊四醇酯的制备方法，包括以下步骤：a)、季戊四醇、C4～C10混合脂肪酸和催化剂混合，在120～180℃条件下进行反应，得到反应产物液；所述C4～C10混合脂肪酸包括3,3,5-三甲基己酸；b)、所述反应产物液在180～220℃条件下进行回流反应，得到季戊四醇酯。本申请通过对季戊四醇和C4～C10混合脂肪酸在120～180℃下反应得到的反应产物液进行回流反应，增加了季戊四醇酯中3,3,5-三甲基己酸结构的含量。
摘要（英）：

The invention belongs to the technical field of chemistry industry and particularly relates to a preparation method of pentaerythritol ester. The preparation method of pentaerythritol ester comprises steps as follows: (a), pentaerythritol, C4-C10 mixed fatty acid and a catalyst are mixed and have a reaction at the temperature ranging from 120 DEG C to 180 DEG C, and a reaction product liquid is obtained, wherein the C4-C10 mixed fatty acid comprises 3,3,5-trimethyl hexanoic acid; (b), the reaction product liquid is subjected to a reflux reaction at the temperature ranging from 180 DEG C to 220 DEG C, and pentaerythritol ester is obtained. The reaction product liquid obtained after pentaerythritol and C4-C10 mixed fatty acid have a reaction at the temperature ranging from 120 DEG C to 180 DEG C is subjected to the reflux reaction, and the content of 3,3,5-trimethyl hexanoic acid structure in pentaerythritol ester is increased.
