Flame retardant CP for cotton fabric - Introduction
Dimethyl 3-hydroxymethylamino-3-oxopropylphosphonate (HMDOBP for short) is an organophosphorus compound.
Nature:
1. the appearance of colorless liquid, with a special smell.
2. Soluble in organic solvents such as ether, alcohol, etc., insoluble in water.
3. It has lower toxicity and higher boiling point.
Use:
1. As the raw material of organic phosphate ester flame retardant, it can improve the flame retardant performance of the material.
2. Used as a linear compatibilizer, it can improve the elasticity and flexibility of polyurethane.
3. in synthetic chemistry, can be used as a protective group and synthetic intermediates.
Preparation Method:
The synthesis of HMDOBP can be obtained by the reaction of methanol and 3-amino-1-hydroxypropanone. The specific steps are as follows:
1. Add 3-amino -1-hydroxy acetone and excess methanol to the reactor.
2. The esterification reaction is carried out at an appropriate temperature, and the reaction time is about several hours.
3. The reaction mixture was cooled and filtered to obtain the product.
Safety Information:
1. HMDOBP should be kept away from fire and high temperature, and stored in a cool and dry place.
2. use to wear protective gloves, protective glasses and protective mask.
3. avoid direct contact with the skin and inhalation of its vapor, such as accidental contact with the skin or eyes, should immediately rinse with plenty of water, and medical examination.
4. in the use and storage process, should comply with the relevant safety procedures.
