摘 要:以烯丙醇、環(huán)氧乙烷、環(huán)氧丙烷為原料,通過(guò)烯丙基低聚物的制備和烯丙基大分子量聚醚的制備兩步反應,合成了烯丙基無(wú)規聚醚,并考察了適宜的合成條件。烯丙基低聚物制備階段,反應溫度為90~110℃,加環(huán)氧乙烷/環(huán)氧丙烷(EO/PO)時(shí)間為2.0~2.5 h,氫氧化鉀用量為烯丙醇質(zhì)量的1%。烯丙基大分子量聚醚制備階段,烯丙基低聚物為起始劑,多金屬氰化物(MMC)催化劑添加量為產(chǎn)品的0.225‰,脫水時(shí)間為60 min,脫水溫度為110℃,反應溫度為110℃左右,加EO/PO時(shí)間為3.5 h。制得的烯丙基無(wú)規聚醚外觀(guān)為無(wú)色透明液體,色澤小于20,不飽和度大于2.23%。

Abstract:Random allyl polyethers were synthesized with allyl alcohol,ethylene oxide and propylene oxide by two steps and at the same time the best synthesis condition was studied. The first step was the preparation of the low weight random allyl polyether. The best reactive conditions were:reaction temperature of 90~110℃,ethylene oxide/propylene oxide (EO/PO)addition time of 2.0~2.5 h and KOH amount of 1% allyl alcohol quality. The second step was the synthesis of the final high weight allyl polyethers. The prepared low weight allyl polyether was used as the starting agent. The reaction condition was following:multi-metal cyanide (MMC) catalyst content of 0.225‰,dehydration time of 60 min,dehydration temperature of 110℃,the reaction temperature of 110℃,EO/PO addition time of 3.5 h. the last two-step product was colorless transparent liquid. The color was less than 20. The unsaturated degree was more than 2.23%.
Key words:allyl alcohol;random polyether;unsaturation;multi-metal cyanide;terminated polyether
