Determination of peroxide in tetrahydrofuran

Tetrahydrofuran and ether are easy to produce peroxide when stored for a long time. Be careful when using. Be sure to detect the peroxide content in the solution first. If more than 0.05% peroxide is present, the peroxide must be removed before distillation. If the peroxide content is 1% or higher, it must be treated by incineration.

Composition and function of cyclohexylamine corrosion and scale inhibitor

In industry, cyclohexylamine is prepared by aniline catalytic hydrogenation, and the commonly used catalyst is cobalt. It can also be divided into two methods: atmospheric pressure and pressurization. In the atmospheric method, the molar ratio of aniline to hydrogen is 1:2, the addition reaction temperature is 150~180 ℃, and the pressure in the reactor is atmospheric. In the pressurization method, the molar ratio of aniline to hydrogen is 1:10, the addition reaction temperature is about 240 ℃, and the pressure in the reactor is 14.61MPa. The fixed bed liquid phase hydrogenation method is adopted.
