It is an efficient catalyst for removing mercaptan in light oil. Gasoline refined from sour crude oil contains higher mercaptan sulfur content.

mercaptan wrapped in fuel is malodorous and corrosive, which reduces the lead content of gas. except, mercaptan is also an oxidation initiator, which can promote the oxidation and condensation of risky components in fuel to gel, resulting in terrible garage balance of gasoline. cobalt phthalocyanine sulfonate is an powerful catalyst for disposing of mercaptan sulfur from heavy oil, and it has the identical effect. whilst in use, dissolve the catalyst in 10% alkali solution, heat it slightly for a time frame, and stir to dissolve it before use.

Resin compatible with polyvinyl chloride, polystyrene, vinyl chloride-vinyl acetate copolymer, nitrocellulose, ethylcellulose, polyvinyl butyal butyal. It is compatible with cellulose acetate and phrochloride cellulose. The cold resistance and light resistance of the product are similar to the tributyl citrate, but water resistance is better. Non-toxic, LD50 = 4000 mg / kg.

Features: Contains two hydroxyl groups and one amino group. Hydroxyl reduces the vapor pressure, increases the solubility, is conducive to the absorption of acid gas, and can increase the concentration, reduce circulation, and reduce energy consumption. The presence of the methyl group in the amino group reduces the alkalinity and activity of the amino group and reduces the CO2 absorption rate.

Sulfur, white and shiny crystal compounds. The taste is bitter, density is 1.405, and the melting point is 180 to 182 ° C. Decomposition when it is hotter, soluble in water, can be dissolved in ethanol when heating, and is slightly dissolved in ether. During the melting, heterogeneity is partialized to form ammonium thiocyanomylisocyanomylocyne. The raw materials used to make drugs, dyes, resins, and plastic powder, and are also used as a vulcanized promoter for rubber, flotal agents for metal minerals.

Methacrylic acid is colorless crystal or transparent liquid with pungent odor. Soluble in hot water, soluble in most organic solvents such as ethanol and ether. Easily polymerized into water-soluble polymers. Combustible, there is a danger of burning in case of high heat and open flame, and it can produce toxic gas when heated.

Acrylic acid has a chemical formula of C3H4O2 and a molecular weight of 72.06.

Acetic acid, also called acetic acid, glacial acetic acid, chemical CH3COOH, is an organic monovic acid, which is the main component of vinegar.

Citric acid (CA), also known as citric acid, with the molecular formula C₆H₈O₇, is an important organic acid. It is colorless crystals, odorless, has a strong acid taste, is easily soluble in water, and is a natural preservative and food additive .

the crystal form of citric acid is exclusive due to distinctive crystallization conditions. it's miles barely weathered in dry air and hygroscopic in humid air. when heated, citric acid may be differentiated into diverse merchandise, that could react with acid, alkali, glycerin, and so on.

Generally speaking, when the energy of the arrangement cannot be satisfied with oxygen breathing, it is arranged that the oxygen that cannot be obtained may not satisfy the quick treatment of oxygen, the concentration of lactic acid will rise. In this case, the acetone dehydrogenase cannot be converted to acetyl coenzyme a, pyruvate start-up. In this case, if the lactate dehydrogenase does not reduce the reduction of pyruvic acid as lactic acid, the composition of triphosphate is inhibited.
