To complement the stater, fractions were made: the trite, the hekte, and so forth in lower denominations.

州硬币是在州面额。为配合州，馏分了：在平凡的，在hekte ，等等低面额。

Vegetable compound wax for emulsion explosive was prepared by mixing vegetable wax with 5th vacuum cuts, 4th foot oil from raw paraffin, crystallite wax and petroleum resin at 120℃ and stirring for 60 minutes. The effect of raw material components on the performance of compound wax was investigated.

以植物蜡与减五线馏分油、减四线蜡下油、微晶蜡和石油树脂为原料，在120℃下加热熔化并搅拌60min条件下，制备了植物型乳化炸药专用复合蜡，并考察了原料组分变化对复合蜡各种性能的影响。

It was found that vegetable compound wax prepared from 16.7% vegetable wax, 18.8%, 58.3%, 4.1% and 2.1% exhibited excellent performance having needle penetration of 68 (1/10) mm, drop melting point of 60℃, kinematic viscosity of 8.13 mm2/s and its oil content was 34.81%. Besides, it was convenient to be used and transported since it was solid at ambient temperature, thus, it was an ideal oil phase material for emulsion explosive.

当植物蜡用量为16.7%、减五线馏分油用量为18.8%、减四线蜡下油用量为58.3%、微晶蜡用量为4.1%、石油树脂用量为2.1%时，制得的植物型乳化炸药专用复合蜡针入度68 （1/10）mm、滴熔点60℃、运动粘度8.13mm2/s、含油量34.81%，其性能优异，常温下呈固态，方便使用和运输，是乳化炸药理想的油相材料。

When no more water separates, distill off the solvent and distill the aldimine.

Deacidification test for lube distillates by a compound solventwas introduced.

一种复合脱酸溶剂被用于润滑油馏分的脱酸实验。

As can be seen in Fig. 5, dipropyl ether will be recovered in the distillate using 1-pentanol, N,N-dimethylformamide and 2-ethoxyethanol as entrainers and butyl propionate is the only entrainer studied that inverts the volatility of the azeotropic mixture.

从图 5可以看出，使用1-戊醇、N，N-二甲基甲酰胺和2-乙氧基乙醇作为共溶剂时二丙醚将在馏分中回收，丙酸丁酯是唯一与共沸混合物挥发性相反的共溶剂。

Dipropyl ether will be recovered in the distillate using 1-pentanol.
