摘要
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%.
