The synthesis and current application situations of efficient series of water-reducers, such as melamines, aliphatics, aminosul-phonic acids and polycarboxylates were introduced emphatically. 并着重介绍三聚氰胺系、脂肪族、氨基磺酸系和聚羧酸系等几类高效减水剂的合成及应用现状。
At the same time, the hydrocarbon generating way of animal is the condensation of aliphatic hydrocarbon, but the algae is due to the break of aliphatics and lateral chain and the aromatics cycle condensation. 同时,动物型有机质成烃途径为脂肪烃缩合,藻类成烃主要是脂族链及侧链断裂和芳环缩聚。
The experiments were carried out to investigate the effect of temperature, initial H2 pressure and soaking time on conversion, oil+ gas yield and aromatics, aliphatics and polar compound yields of ZL and DL coals. 实验研究了液化反应温度、反应时间和氢初压对两种不同变质程度煤的液化性能及芳烃、极性化合物产率的影响规律。
