poisoning

Highly flammable. Slightly soluble in water; Soluble in ethanol and ether. When exposed to oxygen, ethers often form unstable peroxides. Ethyl, isobutyl, ethyl tert butyl, and ethyl tert amyl ethers are particularly dangerous in this regard. Sometimes it can be observed that ether peroxides deposit in the form of transparent crystal Chemicalbooks on containers or along the liquid surface. Colorless liquid with chemical properties. Melting point -92 , boiling point 93.8 , relative density 0.7888 (20/4 ), refractive index 1.4026, flash point -9. Easily soluble in alcohols and ethers, slightly soluble in water.

Glutaraldehyde is a colorless or yellowish clear liquid with a slightly irritating special odor, which is soluble in water and organic solvents such as ether . There are not many free forms in aqueous solutions, with a large number of different forms of hydrates, while most of them are in the form of cyclic hydrates. Glutaraldehyde has active properties and is prone to polymerization and oxidation. It reacts with compounds containing active oxygen and nitrogen. The reaction with proteins mainly involves the reaction of carbonyl groups with amino groups in protein molecules. Among known aldehydes, glutaraldehyde is the best protein crosslinking agent. Glutaraldehyde has excellent bactericidal properties. Glutaraldehyde has little effect on the activity of this enzyme, and most enzymes can be immobilized, cross-linked, and not inactivated under controlled conditions. Due to its numerous excellent properties, glutaraldehyde has attracted great attention and has been widely used.

Sugar Esters E473, CAS No.37318-31-3 , commonly known as Sucrose esters of fatty acids, manufacturing process by esterifying sucrose with fatty acids. By varying the degree of esterification of the sucrose molecule it is possible to obtain emulsifiers with HLB values ranging from 1 up to 16. It is a light yellow powder, a non-ionic surfactant and is used as an emulsifier in dairy products, baked goods, soft drinks, jelly, cake and candy. Sucrose Fatty Acid Esters are a mixture of mono-, di-, and tri-esters of sucrose with fatty acids derived from edible vegetable or hydrogenated vegetable oils and fats.

As an experienced Sugar Esters manufacturer and supplier, we has been supplying and exporting Sugar Esters for almost 10 years, please be assured to buy from us. Any inquiries about price and the market trend please feel free to contact us, we will reply you within 1 working day.

Dimethyl sulfoxide is an extremely important non proton polar solvent that is soluble in both water and organic solvents, it mainly used in dye, acrylic fibers, paint, coating, antifreeze and agriculture.

Application:

1. DMSO can be used for the extraction of arene, also as the reaction medium used for resins and dyes, and applied to acrylic polymerization and spinning solvent.

2. DMSO can be used as an organic solvent, reaction medium and the intermediates of organic synthesis. It is highly versatile. This product has a highly selective extraction capacity, and can be used as the polymerization and condensation solvent of acrylic resin and polysulfone resin, as the polymerization and spinning solvent of polyacrylonitrile and cellulose acetate, as the extraction solvent for separating alkanes and arenes, and as the reaction medium for the arenes, butadiene extraction, acrylic fiber, plastic solvents, organic and synthetic dyes, and pharmaceuticals industries. In the field of medicine, dimethyl sulfoxide has anti-inflammatory and analgesic effect with a strong capability of penetration through the skin, and thus being able to dissolve certain drugs and boost their penetration into the human body to achieve the therapeutic purposes. Taking this carrier property of dimethyl sulfoxide can make it be used as pesticide additives. Add a small amount of dimethyl sulfoxide in some pesticides can facilitate the penetration of pesticides into the plant in order to improve the efficacy. dimethyl sulfoxide can also be used as the dye solvent, dye removing agent, and dye carrier for the synthetic fibers. It can also be used as the absorbent of recycling acetylene and also the modifiers of synthetic fiber, antifreeze agent and the capacitor dielectric, brake oil, and extractant of the rare metals.

3. DMSO can be used as analytic solvents and fixing agent of gas chromatography as well as the solvent for analyzing UV spectra

Propylene carbonate (molecular formula: C4H6O3) is a colorless, odorless, flammable liquid. Miscible with ether, acetone, benzene, chloroform, vinyl acetate, etc., soluble in water and carbon tetrachloride. It has a strong ability to absorb carbon dioxide and is stable in nature. In industry, it is obtained by adding propylene oxide and carbon dioxide under a certain pressure, and then distilling under reduced pressure. It can be used as oily solvent, spinning solvent, olefin, aromatic hydrocarbon extractant, carbon dioxide absorber, dispersant for water-soluble dyes and pigments, etc.

Application
1. It can be used as an excellent medium for high-energy batteries and capacitors in the electronics industry.
2. In the polymer industry, it can be used as a solvent and plasticizer for polymers.
