gross product
Examples
- ( 3 ) prepare a series of solid superacid sample and use as catalyst in the synthesis of lactide to select the most active sample
5小时，解聚反应终止温度在230 - 240 ，粗产物的收率达到90 。 - " floating catalyst " and " catalyst driven by gases " method can synthesize powder of carbon nanotubes on large scale . " vaporizing ferrocene " method can synthesize bulk carbon nanotube array . the production of the first method is 2000g / day , the second one is 500g / day and the third one is loog / day
流化床法和催化剂气动输运法主要产物为纳米碳管粉体，分别每天可以制备2000和500克粗产物；二茂铁蒸发法制备的产物则是定向纳米碳管块体，每天可制备100克纳米碳管阵列块体。 - ( 5 ) the article also investigate the recrystallization condition of crude lactide and point out that it also an important factor have influence on the purification production ratio . ( 6 ) give the kinetics equation of depolymerization reaction . by determination the degree of polymerization ( dp ) of the reaction system , we can get the kinetics data of the reaction
本文建议使用乙酸乙酯和异丙醇混合溶剂( 6 ： 4 )对丙交酯粗产物进行重结晶； ( 6 )提出解聚反应的动力学方程，认为它是一个可近似处理为一级反应的连续反应，并可通过测定体系的平均聚合度的方法来得到包括活化能在内的反应动力学数据。 - While still not evidenced in our experiment , liquid - phase doping of ammonium molybdate solution has been broadly agreed to be able to significantly increase the yield of swnts . we have developed another doping method , solid - phase doping of metal molybdenum at elevated temperature , and discovered that sol - gel prepared catalyst with such doping can be used to grow multi - wall carbon nanotube bundles in a very large scale
对催化剂进行掺钼处理表明，它可显著提高催化剂催化裂解甲烷合成纳米碳管的能力：作者在高温下进行了催化剂掺入金属钼的实验，得到了一种性能优异的催化剂，以此制备的多壁纳米碳管的呈束状分布，所得的粗产物与催化剂之间的重量比达15倍以上。
