一种粗甘油的利用方法
摘要：
一种粗甘油的利用方法，包括将粗甘油、含石油酸的烃油与酯化反应催化剂接触，在温度为200～300℃下进行酯化反应，甘油与石油酸的摩尔比为1～20∶1，接触的时间为1～120min，所述酯化反应催化剂为碱土金属氧化物、镁铝尖晶石、负载碱金属无机盐的碱土金属氧化物、负载碱金属无机盐的镁铝尖晶石中的一种或几种。该方法反应温度低，反应时间短，开辟了粗甘油利用的新途径。
摘要（英）：

The invention relates to a method for utilizing the crude glycerine. The method comprises the steps that the crude glycerine, hydrocarbon oil containing petroleum acid contact with esterification reaction catalyzer to have the esterification reaction at 200 to 300 DEG C, the mol ratio of the glycerine to the petroleum acid is 1 to 20:1, the contacting time is 1 to 120 min, and the esterification reaction catalyzer can be one or more than one of alkali-earth oxide, magnesia alumina spinel, alkali-earth oxide loading base metal inorganic salt, and magnesia alumina spinel loading base metal inorganic salt. The method has the advantages of low reaction temperature and short reaction time, and develops a novel approach for utilizing the crude glycerine.
