Hypophosphorous Acid (HPA) also known as phosphinic acid is a colorless low-melting compound,it is used in applications like; as catalyst during esterification alkyd synthesis, reducing agent for electro less nickel plating, bleaching agent in synthetic fibers, color stabilizer during the manufacturing of chemicals and plastics and is also used in various organic chemistry applications. HPA serves as a neutralizing agent, antioxidant, catalyst in polymerization and poly condensation, and wetting agent. Further, it is used in the formulation of pharmaceuticals, discoloration of polymers, water treatment and retrieval of precious or non-ferrous metals.
Specifications
Aluminum Diethyl Phosphinate is a halogen-free flame retardant based on organic phosphinates. The full name is Aluminum Diethyl Phosphinate.This flame retardant is a kind of white powder or masterbatch, an organic phosphonic acid salt. It is not hydrolyzed, not precipitated, has good self-extinguishing properties into carbon.
Application
It is suited as flame retardant for thermoplastics and thermosets. It has high phosphorus content, good thermal stability and excellent flame retardant efficiency.
As a flame retardant, it can be used separately, also can be used together with other flame retardants. Both two different applications have good effects.
CAS: 225789-38-8 HS code:29319019.90
Product Features
1. ADP is a halogen-free flame retardant based on organic phosphinates. The product achieves its flame retardant effect through intumescence. The thermoplastic polymer with ADP foams and crosslinks on exposure to flame and forms a stable char at the surface acting as a barrier. The protective layer provides a heat insulation effect, reduces oxygen access and prevents dripping of molten polymer.
2. ADP is white particles. The product is not hygroscopic and is insoluble in water and common organic solvents like acetone, dichloromethane, MEK, toluene. The flame retardant is not hydrolyzed, not precipitated, has good self-extinguishing properties into carbon.
Applications
1.ADP is suited as flame retardant for thermoplastics and thermosets. It has high phosphorus content, good thermal stability and excellent flame retardant efficiency.
2.As a flame retardant, ADP can be used alone, can also be used with other flame retardants, both can play a good effect.
3. Application conditions:Processing temperature should not exceed 350C.

PBTCA is widely used in the formulation of efficient scale and corrosion inhibitors and is one of the best performing products. It is also an excellent stabilizer for zinc salts. Widely used as a corrosion and scale inhibitor in circulating cooling water systems and oilfield water injection systems, it is particularly suitable for use in combination with zinc salts and copolymers. It can be used in high temperature, high hardness, high alkalinity, and situations that require high concentration ratios. PBTCA can be used as a chelating agent and metal cleaning agent in the washing industry. PBTCA is generally used in combination with other water treatment agents such as zinc salts, copolymers, organic phosphines, and azoles; If used alone, the dosage is 5-15mg/L.

Propionic acid is an important chemical raw material. Propionic acid and its derivatives are widely used in the synthesis of tree esters, grain preservation, food and feed additives, spices.
The earliest propionic acid was prepared by condensation and separation from the gas produced by charcoal manufacturing and coal coking. In the 1950s, foreign countries developed the process of producing acetic acid by oxidation of light hydrocarbons. The product contains about 10% (propionic acid), which is obtained after separation and purification. In addition to the hydrocarbon oxidation method, the United States also has the method of carbonylation of ethylene, CO and H2 to synthesize propionaldehyde and further oxidation to propionic acid. Due to the development of low-pressure carbonylation process with rhodium phosphine complex as catalyst, propionaldehyde oxidation method has developed rapidly in recent years. This method is superior to the traditional high-pressure method with carbonyl cobalt as catalyst.
Propionic acid, also known as primary oleic acid, is a short chain saturated fatty acid with the chemical formula ch3ch2cooh. Propionic acid is a colorless, corrosive liquid with pungent smell.
