专利汇可以提供Recovery of propylene oxide from contaminants by distillation in the presence of acetone or acetone-methanol mixtures专利检索,专利查询,专利分析的服务。并且Propylene oxide may be efficiently separated from contaminants present in the propylene/oxygen reaction effluent by adding a liquid boiling between 35*C and 100*C, which is not reactive with propylene oxide, to the reaction effluent and distilling propylene oxide from the resulting mixture. Propylene oxide is useful for the production of petroleum demulsifiers, surface active materials, urethane polyols and propylene glycols.,下面是Recovery of propylene oxide from contaminants by distillation in the presence of acetone or acetone-methanol mixtures专利的具体信息内容。

1. A method for recovering propylene oxide from the reaction products of propylene and oxygen which comprises introducing into a distillation column as feed said reaction products and adding in addition to said reaction products a non-reactive liquid selected from acetone or a mixture of acetone and methanol and distilling the resultant mixture under conditions such that said non-reactive liquid essentially physically separates in said column the propylene oxide from the acids or other high boiling materials which are reactive with the propylene oxide and recovering as overhead the propylene oxide and as bottoms said materials which are reactive with the propylene oxide.
2. A method as in claim 1 wherein said non-reactive liquid is a mixture of acetone and methanol.
3. A method as in claim 1 wherein said non-reactive liquid is acetone.
