13517-23-2 - Introduction
SODIUM PHOSPHITE-5-HYDRATE, with the chemical formula of Na3PO3 · 5H2O, is an inorganic compound containing water molecules. The following is a description of its nature, use, preparation and safety information:
Nature:
SODIUM PHOSPHITE-5-HYDRATE is a colorless crystal, soluble in water and alcohol, slightly soluble in ether. It has a certain moisture absorption, easy to absorb moisture from the air. Its solution is alkaline and sensitive to acid.
Use:
SODIUM PHOSPHITE-5-HYDRATE is generally used as a chemical reagent and bactericidal preservative. In chemical experiments, it can be used as an intermediate for the preparation of other inorganic compounds. In the field of horticulture, it can be used to treat seeds and protect fruit trees from the effects of frost.
Method:
SODIUM PHOSPHITE-5-HYDRATE is generally prepared by reacting phosphorous acid with SODIUM hydroxide. First, phosphorous acid is reacted with a small amount of water to produce a phosphorous acid solution. This solution is then reacted with sodium hydroxide solution to give a Sodium phosphite solution. Finally, the crystallization of SODIUM PHOSPHITE-5-HYDRATE was obtained by evaporation and crystallization.
Safety Information:
SODIUM PHOSPHITE-5-HYDRATE is generally relatively safe and harmless under normal conditions, but the following matters still need to be paid attention:
1. Avoid direct contact with skin, eyes and respiratory tract. In case of contact, rinse immediately with plenty of water and seek medical help.
2. Wear protective gloves and goggles when using.
3. Do not mix with strong oxidants and acidic substances to avoid dangerous reactions.
4. Storage should be placed in a dry, ventilated, dark place, away from fire and flammable materials.
it should be noted that the above information is for reference only, before use also need to consult other reliable sources of safety instructions or consulting professionals.
