Abstract: The producing method of the cooling lubricant for home refrigerators using R-134a (1,1,1,2-tetrafluoroethane) as a substitute refrigerant is characterized by reacting an adipic acid with a neopentyl glycol to obtain a dineopentyl glycol adipate, reacting the dineopentyl glycol adipate with a carprylic acid to obtain a mixed product of a neopentyl glycol carprylate of formula (I) [R=C7) and a di(neopentyl glycol monocarprylate) adipate of formula (II) [R=C7 as the cooling lubricant. The mixed product has 10˜35 cst dynamic viscosity at 40 ≦̸C.
Abstract translation: 使用R-134a（1,1,1,2-四氟乙烷）作为替代制冷剂的家用冰箱的冷却润滑剂的制造方法的特征在于使己二酸与新戊二醇反应，得到己二酸二戊二醇，使二新戊基 乙二醇己二酸与卡波酸反应获得式（I）[R = C7]的新戊二醇卡泊酸与式（II）的己二酸二（新戊二醇辛酸酯）[R = C7作为冷却润滑剂]的混合产物。 混合产物在40℃下具有10〜35℃的动态粘度; C。

Abstract: The process method comprises forming overbased calcium sulphonate lubricating oil additives. Calcium sulphonate is produced by reacting carbon dioxide and slaked limes with heavy alkylbenzene sulphonate. Heavy alkylbenzene sulphonate is prepared from heavy alkylbenzene and filtered firstly. Carbon dioxide and slaked limes in mole ratio of 0.65-0.75 are reacted with this filtrate. So filtration performance is highly improved.
Abstract translation: 该方法包括形成高碱性磺酸钙润滑油添加剂。 通过使二氧化碳和熟石灰与重质烷基苯磺酸盐反应制备磺酸钙。 重质烷基苯磺酸盐由重质烷基苯制备，首先过滤。 将二氧化碳和摩尔比为0.65-0.75的熟石灰与该滤液反应。 因此过滤性能得到很大改善。
