2024 The Complete Guide To Isopropyl myristate CAS 110-27-0

1. obtained by esterifying myristic acid with isopropyl alcohol after re-distillation of coconut oil.
2. 200kg of tetradecanoic acid and 450kg of isopropanol are added to the reaction kettle in turn, mixed with 360kg (98%) sulfuric acid, heated at reflux for 10h, recovered isopropanol, washed acid with ice water, then neutralized with 10% aqueous Na2CO3 solution, steamed isopropanol and water at atmospheric pressure, and steamed out the product 185℃/2.0kPa~195℃/2.7kP at reduced pressure.
3. Add 90kg of isopropanol into the reaction kettle, and then add 5% of sulfuric acid as catalyst of the total amount of feed. Slowly add 228kg of tetradecanoic acid under stirring, heat reflux, and continuously dispense water, after the reaction until no water comes out, cool down and take samples to measure the acid value, and the acid value reaches 1.5mgKOH/g as the end point. Add alkali to neutralize the reaction, remove water under reduced pressure, and then remove alcohol under reduced pressure until the acid value is 0.05~1.0mgKOH/g. The finished product will be discharged.

1. used as dispersant of high-grade cosmetics, lipstick, hair cream, lipstick, cleaning cream, fragrance powder and medical ointment, used as emulsifier and wetting agent of cosmetics, also used as perfume fixing agent.
