绿色溶剂DMC在氢化松香甘油酯酸值测定中的应用
Application of green solvent DMC in determining the acid value of hydrogenated rosin glyceride
摘要
Abstract
The toxicity,volatility and ability to dissolve esters of six kinds of solvents were compared.Green solvent DMC,which replace benzene,was studied for determining the acid value of hydrogenated rosin glyceride.Effects of ratio of DMC to ethanol on solution of hydrogenated rosin glyceride were investigated.The results showed that, the best mutual solubility was obtained when the proportion of DMC and ethanol was 2 to 1.The acid value of hydrogenated rosin glyceride was determined by means of the DMC-ethanol solvent in the proportion of 2:1 and the benzene-ethanol solvent in the proportion of 2:1 used in the national standard GB10287-88, respectively,and the correction equation established by the linear regression analysis was Y = 0.995X-0.0852, which make the maximum relative error of the acid value less than 1.56%.关键词
