1974年,金家骏发表了1—1价盐和2—1价盐对乙酸乙酯皂化盐效应的实验结果.该文用Amis 和Jaffe 理论计算的盐效应值与实验值相差较大.1980年,他用定标粒子理论对1—1价盐的盐效应重新作了计算,计算值与实验值符合得较好,所得结果在1980年西安会议上报告,全文在1981年正式发表,但未能导出计算2—1价盐盐效应的公式. Jin Jiajun published the experimental results of the saponification salt effect of 1-valent salt and 2-valent salt on ethyl acetate in 1974. The salt effect value calculated by Amis and Jaffe theory is quite different from the experimental value in 1980. In 1980, He calculated the salt effect of 1-1 salt by calibrated particle theory. The calculated value was in good agreement with the experimental data. The result was reported in Xi’an in 1980 and the full text was published in 1981 but failed The formula for calculating the 2-1 salt salt effect is derived.
