工業(yè)萘的純度一般約為96%。工業(yè)萘進(jìn)一步提純脫除雜質(zhì)及脫硫后,可得到高純度的精萘。

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%含量液體萘,93-95%含量的固體萘,85-90%含量的固體萘,工廠直發(fā),質(zhì)量保證,量大從優(yōu)!

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!

工業(yè)萘是基礎(chǔ)化工原料,主要用于生苯酐、減水劑、擴(kuò)散劑,是生產(chǎn)合成樹(shù)脂、增塑劑、橡膠防老劑,表面活性劑,合成纖維,染料、醫(yī)藥和香料等的原料。

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.

精萘是工業(yè)上最重要的稠環(huán)芳烴，可用于生產(chǎn)苯酐、染料的中間體、橡膠助劑和殺蟲(chóng)劑。精萘可用染料，醫(yī)藥等領(lǐng)域，如生產(chǎn)2-萘酚、1-萘酚和甲萘胺等，也是生產(chǎn)樟腦的主要原料。

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.

一般來(lái)說(shuō)，精萘的升華溫度在80℃- 100℃左右，但具體升華溫度因精萘質(zhì)量和純度的不同可能會(huì)有所差異。在升華過(guò)程中，需要注意以下事項(xiàng)：

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. 升華溫度過(guò)高會(huì)導(dǎo)致精萘的分解和熱降解，在升華過(guò)程中應(yīng)控制溫度不要超過(guò)該精萘的熱穩(wěn)定溫度。

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. 升華后的精萘應(yīng)及時(shí)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. 升華時(shí)應(yīng)采取充分通風(fēng)措施，以防止精萘升華產(chǎn)生的有毒氣體對(duì)人體造成傷害。

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.

總的來(lái)說(shuō)，精萘的升華特性使得其在各行業(yè)得到了廣泛應(yīng)用。在使用精萘?xí)r，應(yīng)注意控制升華溫度和采取有效措施保護(hù)人體安全。

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.
