hydrargyrumoxidflav - Preparation Method
Open Data Verified Data
Mercury (II) nitrate was heated to melt at about 70 ° C., and the water was decrystallized at 200 to 230 ° C., and the thermal decomposition was started from about 270 ° C. To form yellow mercury oxide. Heating to a temperature above 300 ° C. Is then followed to change to a red mercury oxide to produce a finished mercury oxide red.

in brown glass bottles, external carton protection. The net weight of each bottle is 0. 5kg. It's highly drug! Long-term work in the environment of mercury vapor content exceeding the allowable range will cause chronic poisoning, causing a variety of Mental Disorder. It can enter the body through the skin. The skin or eyes should be promptly washed with water, eating into the wrong, to timely gastric lavage and drinking milk or protein. The allowable vapor concentration in air is 0. 05mg/m3, and the others are 0. 1mg/m3 (calculated as Mercury). Production operators should wear work clothes, protective masks and gloves. Protects the respiratory organs and skin. Take a shower after work. Production equipment should be closed and the workshop should be well ventilated. Patients with chronic poisoning should be transferred from work and recuperated. It is toxic. Hazard code: GB Class 6.1 61509. UN NO. 1641; IMDG code 6.1 p. 1. Highly toxic GA 58-938104. Should be stored in a cool, ventilated, dry warehouse, to avoid light. It is not allowed to store and transport together with edible chemical raw materials and acid products.
