  微波辅助 NaHSO4 催化合成蓖麻油酸乙二醇醚酯

  摘要：

  摘要描述了通过高压微波辐射合成几种蓖麻油酸乙二醇醚酯。在特殊的微波反应器中，蓖麻油中的蓖麻油酸在NaHSO4·H2O和二氯甲烷(DCM)存在下与乙二醇醚快速反应。考察了催化剂和溶剂种类、反应温度、时间等反应因素的影响，得到了最佳反应条件。催化剂的活性在第 10 次循环时具有更高的性能，并且获得了优异的周转次数和周转频率值。与传统的回流加热系统酯化相比，微波辅助工艺具有反应时间短、副作用少、收率高、这是发展绿色化学的巨大潜力。图形概要

  A method for increasing ozone concentration in a liquid can include: providing a gas having ozone; introducing the ozone-containing gas into a liquid, wherein the liquid and ozone combination has a temperature between about 0.8 and about 1.5 times the critical temperature of ozone; and increasing isothermally, the pressure of the ozone-containing gas above the liquid to about 0.3 to about 5 times the critical pressure of ozone so as to increase the ozone concentration in the liquid. The temperature is expressed in absolute units (Kelvin or Rankin). The method can be used for removing ozone from a gas or for purifying ozone. The liquid having a high ozone concentration can be used for ozonolysis of a substrate.
