工业萘的纯度一般约为96%。工业萘进一步提纯脱除杂质及脱硫后,可得到高纯度的精萘。

The purity of industrial naphthalene is generally about 96%. After further purification and desulfurization of industrial naphthalene, high-purity refined naphthalene can be obtained.

95%含量液体萘,93-95%含量的固体萘,85-90%含量的固体萘,工厂直发,质量保证,量大从优!

95% liquid naphthalene content, 93-95% solid naphthalene content, 85-90% solid naphthalene content, factory direct delivery, quality assurance, and preferential treatment for large quantities!

工业萘是基础化工原料,主要用于生苯酐、减水剂、扩散剂,是生产合成树脂、增塑剂、橡胶防老剂,表面活性剂,合成纤维,染料、医药和香料等的原料。

Industrial naphthalene is a basic chemical raw material mainly used for producing phthalic anhydride, water reducing agent, and dispersant. It is a raw material for producing synthetic resins, plasticizers, rubber anti-aging agents, surfactants, synthetic fibers, dyes, pharmaceuticals, and spices.

精萘是工业上最重要的稠环芳烃，可用于生产苯酐、染料的中间体、橡胶助剂和杀虫剂。精萘可用染料，医药等领域，如生产2-萘酚、1-萘酚和甲萘胺等，也是生产樟脑的主要原料。

Refined naphthalene is the most important polycyclic aromatic hydrocarbon in industry, which can be used as an intermediate in the production of phthalic anhydride, dyes, rubber additives, and insecticides. Refined naphthalene can be used in fields such as dyes and pharmaceuticals, such as producing 2-naphthol, 1-naphthol, and methylnaphthylamine, and is also the main raw material for producing camphor.

一般来说，精萘的升华温度在80℃- 100℃左右，但具体升华温度因精萘质量和纯度的不同可能会有所差异。在升华过程中，需要注意以下事项：

Generally speaking, the sublimation temperature of refined naphthalene is around 80 ℃ -100 ℃, but the specific sublimation temperature may vary depending on the quality and purity of refined naphthalene. During the sublimation process, the following precautions should be taken:

1. 升华温度过高会导致精萘的分解和热降解，在升华过程中应控制温度不要超过该精萘的热稳定温度。

1. Excessive sublimation temperature can lead to the decomposition and thermal degradation of refined naphthalene. During the sublimation process, the temperature should be controlled not to exceed the thermal stability temperature of the refined naphthalene.

2. 升华后的精萘应及时密封，以防其吸潮。

2. The refined naphthalene after sublimation should be sealed in a timely manner to prevent moisture absorption.

3. 升华时应采取充分通风措施，以防止精萘升华产生的有毒气体对人体造成伤害。

3. Adequate ventilation measures should be taken during sublimation to prevent the toxic gases produced by refined naphthalene sublimation from causing harm to the human body.

总的来说，精萘的升华特性使得其在各行业得到了广泛应用。在使用精萘时，应注意控制升华温度和采取有效措施保护人体安全。

Overall, the sublimation characteristics of refined naphthalene have made it widely used in various industries. When using refined naphthalene, attention should be paid to controlling the sublimation temperature and taking effective measures to protect human safety.
