Preparation method of furfural
Preparation method of furfural: 1. Crushing: use a crusher or hammer to break the corncob. The smaller the particle, the better. 2. Hydrolysis formula: dilute H2so4, catalyst (Fecl3, Nacl3) and three kinds
Major Discovery and Use of Dibenzoylmethane
Dibenzoylmethane derivatives (DBMD) are found in the green tea leaves of the tea plant and have been used in traditional medicine to treat a variety of ailments from infections to rheumatism and as an antioxidant. Their biological activity has not been fully elucidated, but studies in other cell lines have shown activity in p53, retinoblastoma, and mitochondria. Dibenzoylmetha
Operation precautions for dibenzoylmethane

Precautions for the transportation of dibenzoylmethane
Precautions for the transportation of dibenzoylmethane: Vehicles transporting dibenzoylmethane should be equipped with corresponding types and quantities of fire-fighting equipment and leakage emergency treatment equipment. The exhaust pipe of the vehicle carrying this item must be equipped with a fire ar
Properties and Applications of Hydroxyethyl Cellulose
Hydroxyethylcellulose (HEC) polymers are hydroxyethyl ethers of cellulose obtained by treating cellulose with sodium hydroxide and reacting it with ethylene oxide. HEC polymers are primarily used as water-binders and thickeners in many industrial applications, i.e. personal care products, pharmaceutical formulations, construction materials, adhesives, etc., as well as stabilize
How to Give First Aid in Case of Exposure to Dibenzoyl Methane
Dibenzoyl methane is an important β- The light stabilizer and heat stabilizer of the thermoplastic plastics with ketone structure are non-toxic and tasteless. They are widely used in polyvinyl chloride (PVC) plastics and acrylonitrile butadiene styrene (ABS) resins as new auxiliary stabilizers for plastic processing products.
Green Chemical Auxiliary Stabilizer - Dibenzoyl methane (DBM)
Dibenzoylmethane (DBM) is a white or light yellow crystalline powder, which is easily soluble in ether, chloroform, xylene, toluene and sodium hydroxide aqueous solutions, slightly soluble in ethanol, and very slightly soluble in water. The product quality has been tested by the National Research Center for Reference Materials and fully meets the quality standards of similar products abroad. Our company is the largest manufacturer of this product in China.

Production Methods and Application Fields of Hydroxyethyl Cellulose
Hydroxyethyl cellulose (HEC), chemical formula (C2H6O2) n, is a white or light yellow, tasteless, non-toxic fibrous or powder solid, which is prepared by etherification of alkaline cellulose and ethylene oxide (or chloroethanol), and belongs to non-ionic soluble cellulose ethers. HEC has been widely used in oil mining, coating, construction, medicine and food, textile, paper making, polymer polymerization and other fields due to its good thickening, suspension, dispersion, emulsification, adhesion, film formation, moisture protection, and provision of protective c
Physical and Chemical Properties of Dibenzoyl Methane DBM

Colorless inclined square flake crystal, easily soluble in chlorohydrin and chloroform, soluble in sodium hydroxide solution, insoluble in sodium carbonate solution, very slightly soluble in water. As a co stabilizer of calcium/zinc hydroxylate stabilization system, it is used to manufacture PVC mineral water bottles. Analytical reagent for the determination of carbon disulfide and thallium. Es
Production Process and Application of Furfural
Furfural, also known as 2-furaldehyde, its scientific name is α- Furan formaldehyde is a derivative in which the hydrogen atom at position 2 of furan is replaced by aldehyde group. It was originally prepared by co heating rice bran and dilute acid, so it is called furfural. Furfural is formed by hydrolysis of pentosan to produce pentose under the action of acid, and then dehydration and cyclization of pentose. The main raw materials for production are corncob and other agricultural and sideline products. Chemica
