SODIUM PYROSULFITE/SODIUM METABISULFITE
food additive sodium metabisulfite
Sodium pyrophosphate is a white or yellow crystalline powder or small crystal, with sulfurous acid odor, the proportion of 1.4, soluble in water, aqueous solution is acidic, and strong acid contact with the release of sulfur dioxide and the formation of the corresponding salts. Sodium pyrophosphate can not be stored for a long time, and the packaging should be sealed to prevent air oxidation. Soluble in water soluble in glycerin, slightly soluble in ethanol. Moisture easily decomposed, exposed to the air easily oxidized into sodium sulfate.
1) Food Grade: bleach agent(e.g. candies, cake, bamboo shoots, etc); loose agent(e.g. bread, cracker etc); antiseptic and germicide(e.g. fruit juice, tinned food, brews, the cereals food is defended storage etc);
2) Industry grade: mordant of printing and dyeing; dechlorinate of textile after bleaching; sulphonated agent and reducer of chemical industry and pharmacy; bleach of paper pulp, bamboo and timber bleach of stap; treatment agent of waste water; rubber solidifying agent perfume industry is served as hydro carbon perfume aldehyde.
The hide profession employ to do to molt dose and piable dose and wearproof dose; sewage treatment, and so on.
3). Pharmaceutical grade: in chemical synthesis in the production of acrylic fibre, vitamin k, vitmin A, pharmaceutical intermediates, etc.
4). Photo grade: the sensitize industry is served as the developing agent reductant and the protection of fixing bath dose.
Storage: store the products in dry and cool place.
Appearance: white free flowing fine crystal or powder.
Property: white or light yellow crystal powder, a strong smell of sulfur dioxide, relative density is 1.4, easy to dissolve in water and glycerin, water solution. It has acidity, and its solubility will become large while raising the temperature and is less to dissolve in ethanol.
