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
1
H 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.
本发明涉及将
蓖麻油中存在于85-90%的
蓖麻酸的
化学结构进行改性,制备三酰
氧基烷基
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,随后酰化羟基以获得富含9,10,12-三酰
氧基十八
碳酸烷基
酯的
脂肪酸烷基
酯混合物。从粗产品中纯化出9,10,12-三酰
氧基十八
碳酸烷基
酯,并通过1H NMR研究进行表征。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.),倾点,闪点和
铜片腐蚀,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。
