Yield:-

Reaction Conditions:

with solid acid catalyst at 230 - 260; for 4 h;Green chemistry;Temperature;

Steps:

3
Weigh in proportion quantitative stearate, ethylene glycol, the solid acid catalyst is equal to 1000ml four-necked flask reactor, the flask was placed in a heating jacket; on the flask four outlets are connected to a reflux condenser, glass thermowell , manifold, adjustable straight tubes;The reactor was heated, the heating temperature is set initially 230 ° C, the reaction temperature is adjusted depending on the reaction conditions; 230~260 ° C at the reaction temperature for 4 hours; acid value measurement specimen sampling, in accordance with GB / T9104-2008 Standard Determination of acid value (mgKOH / g); for glycol diester of stearic acid, when 5mgK0H / g or less acid value of the sample, to stop the reaction, and filtered to give a wide product; taking the product sample analysis: Electronics weighing scales, measuring the acid value (mgKOH / g), calculated in accordance with its transfer GB / T9104-2008 standardRate (Q) is: play therapy wash logo move Chun Yan instrument code mining town. _ ^ _ Hard hair honor code
