Question

请哪位大虾帮忙翻译成英语，要准确些的，谢谢您了

甲缩醛是一种天然气和煤化工重要的衍生产品，是一种环保型的有机溶剂，在清洁剂、油漆、柴油改性添加剂等多个领域得到广泛的应用。催化精馏制备甲缩醛工艺目前国内尚未形成大规模工业化生产，具有一定的开发应用价值。
本文确定了催化精馏法制备甲缩醛的多项工艺参数，通过对催化剂的选择与用量、配料比例、反应各段的温度压力和回流比例的实验研究得到最佳工艺条件：配料比甲醇与甲醛的摩尔比为1:1～2:1，预反应温度40～60℃，催化剂总量占总体积的30%，精馏塔塔顶、催化层和塔底反应温度温度分别为30～50℃、50～60℃和75～90℃，得出塔顶压力小于2kg/cm3、塔底压力小于3.5kg/cm3和塔顶馏出和回流的物质的量比控制在1：1～1.4：1。在最适宜参数条件下进行的重复性实验结果验证良好。
不要翻译器翻译出来的，谢谢。用在较正规的材料上的，谢谢，请您费心了

Answer 1

Armour acetals is a kind of natural gas and coal chemical industry important derivative products, is an environment-protecting organic solvent, in cleaner, paint, diesel performance additives etc widely application. Catalytic rectification preparation armour acetals technology at present domestic has not been formed mass industrial production, have certain development application value.
This paper determines the catalytic rectification legal system for a number of process parameters acetals, through the choice of catalysts and the dosage, batching scale, reaction temperature and pressure of feedrate and reflux ratio, experimental study of optimal process conditions: ingredients than methanol and formaldehyde for the molar ratio of 1:1 ~ 45.16% prestressing, reaction temperature 40 to 60 ℃, catalyst share of total volume of 30%, distillation tower, catalyst layers and the bottom and reaction temperature temperature respectively is 30 ~ 50 ℃, 50 ~ 60 ℃ and 75 ~ 90 ℃, draw the tower 2kg/cm3, less stress than 3.5 kg/thetower bottom pressure cm3 and tower fractions out and backflow of amount of substance ratio control in 1:1 ~ 1.4:1. In optimal parameters under conditions of repeatability of experiment results show good.希望能帮到你

Answer 3

Methylal is a significant natural gas and coal chemical derivatives, is an environmentally friendly organic solvents, detergents, paints, diesel modified additives and other fields are widely used. Preparation of catalytic distillation process methylal not yet formed a large-scale domestic industrial production, development and application of a certain value. We have identified a catalytic distillation methylal prepared a number of process parameters on catalyst selection and dosage, the proportion of ingredients, reaction temperature and pressure of each segment and return the best ratio of experimental research conditions: mixture ratio of methanol and formaldehyde molar ratio of 1:1 ~ 2:1,Pre-reaction temperature is 40 ~ 60 ℃, catalyst amount of the total volume of 30% of the distillation tower, reaction temperature, catalyst layer and bottom temperatures were 30 ~ 50 ℃, 50 ~ 60 ℃ and 75 ~ 90 ℃, was the top pressure is less than 2kg/cm3, bottom and top pressure is less than 3.5kg/cm3 distillate and the return of control in a 1:1 molar ratio of ~ 1.4:1. Parameters at the optimum conditions Experimental results show good repeatability.
