酒精是合成橡胶、医药、农药、有机合成等生产中必不可少的原料和溶剂。用粮食生产酒精,则每吨酒精将消耗三吨多粮食,不仅造成与民争粮的局面,并且使产品成本大为提高,影响工业的发展。随着石油开采及炼制工艺的飞速发展,将可获得日趋丰富的乙烯资源。以乙烯为原料用硫酸水合法生产酒精,不仅酒精收得率高,而且对乙烯纯度要求不严,故生产成本低,同时可节约大量粮食供民用。仅 Alcohol is an indispensable raw material and solvent in the production of synthetic rubber, medicine, pesticide and organic synthesis. Producing alcohol with grain will consume more than three tons of food per tonne of alcohol, which will not only result in competing with the people for food, but will also greatly increase the cost of products and affect the development of the industry. With the rapid development of oil extraction and refining processes, an increasingly abundant ethylene resource will be obtained. Ethylene as raw materials with sulfuric acid hydration production of alcohol, not only high alcohol yield, but also lax requirements of ethylene purity, so the production cost is low, while saving a lot of food for civilian use. only
