Purification of propylene oxide by treatment with calcium hydroxide in glycerol or sugar water |
摘要 |
Methyl formate is removed from propylene oxide by treatment with aqueous calcium hydroxide slurry. Calcium hydroxide solubility is increased by adding a solubilizer selected from the group consisting of sucrose, fructose, maltose, glycerol and mixtures thereof. Methyl formate hydrolysis rate is improved by propylene oxide/water ratio control. Addition of an aldehyde scavenger improves propylene oxide purity.
