石油化学是新兴工业,新的合成法也正在不断地出現,相信今后这种趋势更要加强。例如奥綸类合成纤维主要原料丙烯腈的合成方法,就改用丙烯与氨作原料而代替了从来使用的以氫氰酸与乙炔作原料的方法。目前在空气存在下操作的苏和法,正在以很大的規模实行工业化生产中。再有作为原料之一的氫氰酸的制造也已进入可以使用C_3—C_4的气体或液体的碳氫化合物代替甲烷为原料的阶段了。石油化学方面新的发展,无論如何总在于氧化方面。特别是过氧化氢的制造,出现了不用过去的电解法,而用非电解法,相信确定了这种廉价的制造法之后,低温液相法将要代替过去的高温气相法而大大地
Petrochemical industry is emerging, the new synthesis method is also constantly emerging, I believe this trend should be strengthened. For example, Aramid fiber synthetic raw materials, the main raw material for the synthesis of acrylonitrile, propylene and ammonia instead of using raw materials instead of the original use of hydrogen cyanide and acetylene as raw materials approach. The Soviet Union and France, currently operating in the presence of air, are implementing industrialized production on a large scale. The production of hydrocyanic acid, one of the raw materials, has also entered the stage in which methane or methane can be used instead of methane as a gas or liquid C_3-C_4 gas. New developments in petrochemistry are always in the area of oxidation. In particular, hydrogen peroxide has been produced without using the conventional electrolysis method. However, with the non-electrolytic method, it is believed that after such an inexpensive manufacturing method is confirmed, the low-temperature liquid phase method will replace the conventional high-temperature gas phase method and greatly
