空气/花卉界面上的脂肪醇聚氧乙烯醚保鲜性能研究

Investigation and Manufacture of Polyoxyethylene Fatty Alcohol Ether on Air Flower Interface

以十八醇为原料 ,通过Willamson合成法合成了环氧乙烷加成数为n =2、3的十八醇聚氧乙烯醚。经减压蒸馏提纯后 ,利用铺展溶剂将其喷雾于切花花卉表面形成一层单分子膜 ,能够有效地抑制切花花瓣表面水分蒸发 ,从而可以延缓切花衰老、延长其瓶插寿命 (其处理的切花寿命是对照的 1 5倍 )。

Polyoxyethylene fatty alcohol ether(N=2、3) was synthesized from octadecanol through Williamson's synthesized theory after decreased press distillation purification,sparred it on the cut flower interface formed a monolayer through exhibit solvent,the result suggested that polyoxyethylene fatty alcohol ether monolayer could retard evaporation of water on cut flower interface.Cut flower longevity of use it is 1.5 times comparison with purity water,so it could postpone cut flower longevity,make its bottle insert longevity become longer.
