    • Produce polyol esters from natural oils or derivatives thereof by: (i) subjecting an admixture that comprises (a) a natural oil component consisting essentially of at least one hydroxylated triglyceride having at least one hydroxyl group, and a solubility parameter (a), and (b) a polyether component consisting essentially of at least one polyether polyol having a boiling point above that of glycerin and having a solubility parameter (b); wherein | (a) - (b)|, as measured on the MPa1/2 scale at most about 2 MPa1/2, to transesterification conditions using at least one transesterification catalyst; and (ii) removing sufficient glycerin to drive formation of at least one polyol ester from the polyether polyol and at least one fatty acid from the hydroxylated triglyceride. The polyol esters, whether capped or not, are characteristically homogeneous and have utility in, for instance, elastomers, coatings, adhesives, sealants, foams, functional fluids, lubricants, surfactants, wetting agents, dispersing agents, power transmission fluids, oil and gas exploration fluids, industrial and institutional cleanings, metal working fluids, and quenchants.
    • 通过以下方法由天然油或其衍生物生产多元醇酯:(i)使包含(a)主要由至少一种具有至少一个羟基的羟基化甘油三酯和溶解度参数(a)组成的天然油组分的混合物和 (b)基本上由至少一种沸点高于甘油并且具有溶解度参数(b)的聚醚多元醇组成的聚醚组分; 其中| (a) - (b)|在至少约2MPa1 / 2的MPa1 / 2标度下测定为使用至少一种酯交换催化剂的酯交换条件; 和(ii)除去足够的甘油以驱动从聚醚多元醇和至少一种来自羟基化甘油三酸酯的脂肪酸形成至少一种多羟基酯。 无论是否加盖,多元醇酯都是特征均匀的,并且在例如弹性体,涂料,粘合剂,密封剂,泡沫,功能流体,润滑剂,表面活性剂,润湿剂,分散剂,动力传动液,油和气体 勘探流体,工业和机构清洁,金属加工液和淬火剂。
