1、精萘是最重要的有机化工原料。 针对目前精萘的实际生产情况,介绍国内外精萘的4种主要生产方法:区域熔融法、分步结晶法、催化加氢法及动态结晶法。

1. Refined naphthalene is the most important organic chemical raw material. Based on the current actual production situation of refined naphthalene, this article introduces four main production methods of refined naphthalene at home and abroad: regional melting method, stepwise crystallization method, catalytic hydrogenation method, and dynamic crystallization method.

2、萘,又称并萘,是一种无色有光泽的片状结晶。不溶于水,易升华,能随水蒸气挥发,有特殊气味。是工业上最重要的稠环芳烃,可用于生产、染料的中间体、橡胶助剂和杀虫剂。根据纯度不同,萘可分为工业萘和精萘。工业萘的纯度一般约为96%。

2. Naphthalene, also known as naphthalene, is a colorless and glossy crystalline flake. Insoluble in water, prone to sublimation, can evaporate with water vapor, and has a special odor. It is the most important polycyclic aromatic hydrocarbon in industry, which can be used as an intermediate in production, dyes, rubber additives, and insecticides. According to different purities, naphthalene can be divided into industrial naphthalene and refined naphthalene. The purity of industrial naphthalene is generally about 96%.

3、萘是工业上重要的稠环烃,主要用于生产、各种萘酚、萘胺等,是生产合成树脂、增塑剂、染料的中间体、表面活性剂、合成纤维、涂料、农药、医药、香料、橡胶助剂和杀虫剂的原料。

3. Naphthalene is an important polycyclic hydrocarbon in industry, mainly used in the production of various naphthols, naphthylamines, etc. It is an intermediate in the production of synthetic resins, plasticizers, dyes, surfactants, synthetic fibers, coatings, pesticides, pharmaceuticals, spices, rubber additives, and insecticides.

4、精萘的自然属性为:不溶于水、易升华、能随水蒸气挥发、有特殊气味,它是一种无色有光泽的片状结晶,可以用于生产、染料的中间体、橡胶助剂和杀虫剂,是工业上最重要的稠环芳烃,工业萘的纯度一般约为96%。

4. The natural properties of refined naphthalene are: insoluble in water, easy to sublime, able to evaporate with water vapor, and having a special odor. It is a colorless and glossy crystalline flake that can be used as an intermediate in production, dyes, rubber additives, and insecticides. It is the most important polycyclic aromatic hydrocarbon in industry, and the purity of industrial naphthalene is generally about 96%.
