_ _ Preferred hydrazine hydrate hydrazine hydrate East-Chemical (certified merchants)

Hydrazine industrial production methods are Rasi law, urea method, ketazine law and Hydrogen Peroxide 40 four kinds of hydrazine hydrate, currently the main use of urea in the process. 1. Urea Oxidation 10% sodium hypochlorite solution and 30% caustic mix 80 hydrazine hydrate, and then cooled, adjust the mix, and then cooling, a mixture of chlorine and alkali adjustment to 1: 1.8 weight ratio, into the reaction pot . Then add the right amount of potassium permanganate, stirring 11:50 urea solution, heated to about 103-104 ℃ feed liquid boiling up. Urea amount calculated according to available chlorine 85 hydrazine hydrate, the weight ratio of available chlorine is 76:75. The crude product of the oxidation of hydrazine was added to the evaporator water vacuum distillation, hydrazine gas and water vapor through the air is introduced into blind acceptance of the autoclave was first concentrate. Hydrazine light water reactor to be supplied from the accepted sieve column was subjected to vacuum concentration, hydrazine hydrate content reaches a predetermined value. When the content of ≥40% urea 770 890030% sodium hypochlorite sodium hypochlorite, caustic 52002. ammonation first formulated by the chlorine and caustic soda as sodium hypochlorite, then synthesized at 3.922 × 107Pa pressure and 130-150 ℃ temperature, the reaction liquid hydrazine hydrate, After stripping to remove excess ammonia, and then evaporated desalination and distillation products hydrazine hydrate]. At present, China hydrazine hydrate producers more scattered distribution, small-scale, high energy consumption, low efficiency, the technology behind the production of urea-based, unstable product quality, with a big gap between the international level, we can not participate in international competition and to meet domestic foreign market demand. In view of this situation, we made the following recommendations: (1) In recent years, a large domestic market supply and demand gap of hydrazine hydrate, resulting in rising prices, along with the rapid development of China's growing engineering plastics, pharmaceuticals, pesticides and boiler oxygen scavenger demand, hydrazine hydrate demand will maintain growth momentum, therefore, imperative to develop the industry of hydrazine hydrate. (2) from other environmental, product quality and cost into account hydrazine hydrate, urea law will eventually be eliminated, and the hydrogen peroxide method obvious advantages, our country should be eliminated as soon as possible backward production technology, use of advanced technology to improve product quality. (3) some domestic research institutes of hydrazine hydrate hydrogen peroxide production process has been carried out for many years in research and development and breakthroughs, but the maturity of the technology is different, so companies want the new device must be on technology development units to conduct a comprehensive study select reliable technology units to cooperate. _ _ Preferred hydrazine hydrate hydrazine hydrate East-Chemical (certified merchants) are provided by Jinan East-Chemical Co., Ltd.
