The present invention relates to modification of the chemical structure of ricinoleic acid, which is present to an extent of 85-90 % in castor oil into triacyloxy alkyl ester derivatives. Accordingly, 9,10,12-trihydroxy octadecanoic acid rich fatty acid mixture was prepared from castor oil and converted to their alkyl esters followed by acylation of hydroxy groups to get 9,10,12-triacyloxy octadecanoic acid alkyl ester rich fatty acid alkyl esters mixture. The 9, 10, 12-triacyloxy octadecanoic acid alkyl esters were purified from the crude product and characterized by 1H NMR studies. The crude products were also evaluated for acid value (A.V.), hydroxyl value (H. V.), iodine value (I. V.), viscosity, viscosity index (V.I.), pour point., flash point and copper strip corrosion and found to be potential base stocks for hydraulic, metal working fluids and other industrial fluids.
本发明涉及对蓖麻油中含量为85-90%的蓖麻酸的化学结构进行修改,将其转化为三酰氧烷基酯衍生物。因此,从蓖麻油中制备了富含9,10,12-三羟基十八碳酸的脂肪酸混合物,并将其转化为它们的烷基酯,然后通过酰化羟基来获得富含9,10,12-三酰氧基十八碳酸烷基酯的脂肪酸烷基酯混合物。从粗产品中纯化了9,10,12-三酰氧基十八碳酸烷基酯,并通过1H核磁共振研究对其进行了表征。还评估了粗产品的酸值(A.V.)、羟值(H.V.)、碘值(I.V.)、粘度、粘度指数(V.I.)、凝固点、闪点和铜片腐蚀性,并发现它们是液压、金属加工液和其他工业液体的潜在基础油。
