1.Grade:Industrial grade 2.Physical and chemical
properties:sodium hydroxide, commonly known as caustic soda,
caustic soda, caustic soda, pure product is colorless and
transparent crystal. Density of 2.**0 g/cm after. The melting
temperature of **8.4 ℃. The boiling point of ***0 ℃. Industrial
products contain small amounts of sodium chloride and sodium
carbonate, which are white opaque crystals. There are block, flake,
granular and rod. Sends out when the ammonia flavor, has the strong
alkali, strong causticity, generally to flake or granular form,
soluble in water, soluble in water heating) and formation of
alkaline solution, deliquescence: easy to absorb water vapor in the
air (deliquescence) and carbon dioxide (bad), sodium hydroxide in
water treatment can be used as alkaline cleaner, soluble in alcohol
and glycerin; Insoluble in propanol, diethyl ether. It also has a
corrosive effect on sodium carbon at high temperature.
Disproportionation reaction occurs with halogens such as chlorine,
bromine and iodine. Neutralizing with acids to form salt and water
3.Product application:
