In this paper we studied the simple history,principle,process and selective method of carrier and medium of production of acetone and butanol with fermentive method of clostridium aceto-butylicum. 本文研究了丙丁菌发酵法生产丙酮和丁醇的简史、原理、过程,以及载体和培养基的选择方法。
Method: To extract lecithin from egg yolk with acetone and ethanol. 方法:用丙酮、乙醇提取蛋黄中的卵磷脂。
The correlation r in methanol,acetone,chloroform and butanol was respectively 0.999 9,0.999 9, 0.998 4 and 0.999 8.The recovery was 96.0%,97.3%,81.1% and 93.9% with RSD 2.7%,1.9%,8.8% and 2.5%,(n=5) respectively. 甲醇、丙酮、氯仿、正丁醇线性关系r分别为 0 .
Using sodium bisulfate as the catalyst,butyl butyrate was synthesized from butyric acid and butanol. 以硫酸氢钠为催化剂,丁酸与丁醇为原料合成了丁酸丁酯。
A hydrocarbon, C6H3(CH3)3, occurring in petroleum and coal tar or synthesized from acetone and used as a solvent. 三甲苯一种碳氢化合物，化学式为C6H3（CH3）3，能从石油和煤焦油中提取或用丙酮合成，被用作一种溶剂
