Suggest Uses:

Mainly for the production of stearic acid salts: Widely used system for cosmetics, plastic cold-resistant plasticizer, release agent, stabilizer, surfactants, rubber vulcanization accelerator, waterproof agent, polishing agent, metal soap, metal mineral flotation agent, softeners, pharmaceuticals, and other organic chemicals.
In addition, oil-soluble pigments can be used as solvents, crayons transfer slip agent, waxed paper lighting agent, stearic acid glyceride emulsifier, etc..

Packing :25/50kg in PP bag ,25MT/20GP

Product Storage:

in dry warehouse ventilation should be more than 10mm from the ground to avoid damp  products in the above-mentioned conditions, from the date of delivery for one year shelf life.


Q: Sugar, fat, and so on a variety of organic matter is full of different units of the heat of the small box. (Save the heat the most efficient, the least loss of heat the most practical and most economical box).
Understand enough messy
Q: Is polyethylene a derivative of hydrocarbons?
The definition is yes
Q: Alcohols and carboxylic acids in the hydroxyl group, the oxygen atoms are sp3 hybrid or sp2 hybrid
In the carbonyl R-COOH carbon, one of the O can only form a double bond with C, that is, a sigma bond and a Pi bond, and also with R and OH each form a sigma key, a total of four keys, C on the most The outer layer and no electrons to form solitary electrons. According to the principle of hybrid, because there are only three sigma, need to participate in the hybrid track can only be three, that is, sp2 hybrid.
Q: What is the proportion of hydrocarbons synthesized by Fischer-Tropsch Synthese in liquid fuels consumed by Nazi Germany? What are the proportions of these hydrocarbons as an industrial raw material into their military industry, in addition to fuel? At that time, did the Fischer-Tropsch preparations occupy an important position in Nazi Germany's military industry or heavy industry?
Now, the improved economic benefits of FT still limit its further development. Some of the enterprises' coal indirect liquefaction projects have been terminated (for example, Shenhua Group), coupled with the impact of breakthrough development of shale oil technology, the development prospect of coal indirect liquefaction not optimistic.
Q: Derivatives of vinyl acetate
Vinyl acetate can produce reactions that occur most of the olefins or esters. Such as the addition of bromine to form dibromide, the addition of hydrogen halide to produce vinyl haloacetate, which is the only way to produce the substance because there is no corresponding halohydrin. The addition of acetic acid under palladium catalysis can produce ethylene diacetate and CH3CH (OAc) 2. The latter can undergo a transesterification reaction with many carboxylic acids. As an alkene, vinyl acetate can also undergo a Diels-Alder reaction and a 2 + 2 ring addition
Q: Are hydrocarbons all organic?
The organic matter is an abbreviation of an organic compound and refers to a compound containing a carbon (C) element (a carbon-containing oxide such as CO.CO2 and a carbonate and bicarbonate-containing compound such as CaCO3.NaHCO3, a metal carbide such as CaC2 , Cyanide, etc.), simply say that most of the carbon-containing compounds and their derivatives of all elements and their compounds, while carbonates, carbonates, bicarbonates and other compounds, although the hydrocarbon is inorganic.
Q: Other corals are because the color of the corals show colorful, why only the red coral is the exception of it? did not find the reasons for the big god to explain
Calcium coral is the main component of calcium carbonate, in addition to about 3% of magnesium carbonate and 1.5% to 4% of organic matter, and trace amounts of silicon and iron. The presence of organic matter increases the toughness of corals, making it better for processing and polishing. Calcium coral colors are mostly white or gray, but when it contains a considerable amount of different impurities, it is possible to show red, pink, orange, yellow, blue, purple and other colors. Therefore, by the living environment and many other factors, the same kind of coral can have different colors, and different types of corals and stars showing the same color. Red coral is really because of carotene.
Q: What is organic?
Simply refers to the organic ingredients containing organic ingredients. The real organic cosmetics are organic plants as the main raw material, do not add artificial spices, artificial colors, oil-free ingredients, the added preservatives and surfactants must be strictly limited, and the manufacturing process to comply with the relevant provisions, can not use animals Experiments and the use of radiation sterilization products. In general, the certification of organic skin care products must meet the following conditions: First, the organic environment, the closest growth of natural growth, production base (ie, the environment) are not damaged, water (irrigation water), soil (soil ), Gas (air) is not contaminated. Second, organic cultivation, no artificial fertilizer irrigation or artificial feed, without antibiotics, chemical insecticide, without genetic variants. Third, the organic processing and production projects, including the harvest after washing, finishing, packaging, processing, transportation, storage, sales and other sectors) did not subject to secondary pollution.
Q: Is the reaction of carboxylic acid and ammonia easy?
Easy acid and alkali reaction
Q: How the most primitive life on earth is produced under what conditions
These macromolecules are not in the modern sense of the protein and nucleic acid polymer, but a variety of amino acids, nucleosides, phosphoric acid, carbohydrates and some other small molecules of the disorder of the polymer, when the nucleoside and phosphoric acid composition of nucleoside Acid, and gradually form a nucleotide chain, the formation of these nucleotide chain of the amino acid on the formation of the field of binding force, and then assembled peptide chain. Or by the combination of a variety of amino acids into peptide chain formed by the force field on the surrounding nucleus formation field binding effect, and then assembled the nucleotide chain, with the formation of peptide chain and nucleotide chain longer and longer , The molecular weight is growing, and ultimately the formation of nucleic acids and proteins, nucleic acid and protein formation is the product of interaction with each other, is generated at the same time.
