亚硫酸化梓油研制及应用

Investigation and Application of Bisulfited Catalpic Seeds Oil

本文以湖北沙市盛产的梓油为主要原料，采用以焦亚硫酸钠为磺化剂，在催化剂、乳化剂存在下进行氧化、亚硫酸化得到棕色或桔黄色磺化梓油，其结合硫含量在９％～１３％（以ＳＯ３计）。

Abstract The calculated modified catalpic seeds oil, a certain amount of Catalysts K_2 and K_3 are added into a 4-mouth reactive flask, raised temp. to 60～90℃, stirred, oxidized at this temp. for 0.5～4 hr, added by the quantitive emulsifier and saturated solution of sulfite, followed by the refluxing reaction at 60～90℃ for 6～12 hr. Then the emulsifying reaction and dehydration are carried out at the same temp. for 3～6 hr. The product is a viscous yellow liquor in appearance, with SO_3 contents of 12.46%.
