实验步骤: Approximately 360 g of the 1,2-mixed pentadecanedioloctadecanediol (obtained from Viking Chemical Co. as Vikol 158 containing about 28% 1,2-pentadecanediol, about 28% 1,2-hexadecanediol, about 28% 1,2-heptadecanediol and about 16% 1,2-octadecanediol) were charged to a glass reactor equipped with heater, agitator, Dean-Stark tube with condenser and provision for blanketing the vapor space with nitrogen. The contents were heated to 70° C. to liquify and 55 g of dimethyl hydrogen phosphite were slowly added. The reaction mixture was heated to 110° C. and held for 2 hours, held at 120° C. for 1 hour, and held at 130° C. for 1 hour. During this reaction period, methanol distilled over and condensed into the trap. The crude product was vacuum stripped at 150° C. to remove volatile materials. 379 g of finished additive were produced. The product was an amber fluid which became waxy on cooling. equipped with heater, agitator, Dean-Stark tube with condenser The reaction mixture was heated to 110° C. held at 120° C. for 1 hour held at 130° C. for 1 hour distilled over and condensed into the trap stripped at 150° C. to remove volatile materials 379 g of finished additive were produced on cooling
