Chemical Auxiliary Agents

Chemical auxiliary agents can be used to change the chemical reaction rate (increase or decrease) in the chemical reaction without changing the chemical equilibrium, and the mass and chemical properties of the reactants are not changed before and after the chemical reaction. According to statistics, about 90% of the industrial processes use Chemical auxiliary agents, such as chemical, petrochemical, biochemical, environmental protection and so on. There are a wide variety of chemical auxiliary agents, which can be divided into liquid and solid according to their state. The phase states of the reaction system are divided into homogeneous and heterogeneous catalysts. The homogeneous catalysts have acid, alkali, soluble transition metal compounds and peroxide catalysts. Chemical auxiliary agents plays an important role in the modern chemical industry, for example, the use of iron catalyst in the production of synthetic ammonia, the production of vanadium catalyst in the production of sulfuric acid, the polymerization of ethylene and the production of three synthetic materials, such as butadiene rubber, use different catalysts.

Chemical auxiliary agents Attention:

[ operation notice]

Closed operation, local exhaust. Prevent steam from leaking into the air of the workplace. Operators must undergo special training and strictly abide by the rules of operation. It is recommended that operators wear self-priming filter respirators (semi masks), wear chemical safety glasses, wear protective clothing and wear rubber gloves. Keep away from fire and heat sources. Smoking is strictly prohibited in the workplace. The use of explosion-proof ventilation systems and equipment. Before welding liquid and steam, welding and cutting operations can not be carried out. Avoid smoke. Avoid contact with oxidants. Equipped with corresponding varieties and quantities of fire fighting equipment and leakage emergency handling equipment. The empty container may remain harmful.

[storage notice]

Store in a cool, ventilated storeroom. Stay away from fire and heat. Prevent direct sunlight. Keep the container seal. It should be kept separately from the oxidizing agent and avoid the mixture. Equipped with the corresponding variety and quantity of fire equipment. Emergency handling equipment and suitable storage materials should be provided in the storage area.
