Chemical Detection of Sodium Ethyl Xanthate

Posted in General | 10:47

Sodium ethyl xanthate can be identified through optical absorption peaks in the infrared and ultraviolet (300 nm) ranges. There are several methods for chemical detection. First, Xanthate can be reacted with a copper sulfate or copper tartrate resulting in a copper xanthate residue which is detected with iodine. It has an advantage of being is insensitive to sulfite, thiosulfate and carbonate impurities. Second, In the mercurimetric method, xanthate is dissolved in 40% aqueous solution of dimethylamine, followed by heating and titration with O-hydroxymercuribenzoate. The product is detected with thiofluorescein. At last, Perchloric acid method involves dissolution of xanthate in water-free acetic acid. The product is titrated with perchloric acid and detected with crystal violet.

New Introduction to Light Stabilizers 292

Posted in General | 11:06

Stabilizers for polymers are used singly or in combinations to prevent the oxidation, chain fission, uncontrolled recombinations and cross-linking reactions that are caused by photo-oxidation of polymers. Polymers become weathered by the direct or indirect impact of heat and ultraviolet light. Light Stabilizers 292 may be used after adequate testing for automotive coatings, coil coatings, wood stains or do-it-yourself paints, radiation curable coatings. It can be handled as industrial chemical provided the following handling precautions are observed: work in a clean and well ventilated area avoid contact within skin, wear goggles to avoid irritation of the eyes.

New Introduction to Methanol

Posted in General | 10:47

Methanol is used on a limited basis to fuel internal combustion engines. Pure methanol is required by rule to be used in Champcars, Monster Trucks, USAC sprint cars (as well as midgets, modifieds, etc.), and other dirt track series, such as World of Outlaws, and Motorcycle Speedway. Methanol fuel also has been proposed for ground transportation. The chief advantage of a methanol economy is that it could be adapted to present internal combustion engines with a minimum of modification in both engines and infrastructure to store and deliver liquid fuel.

Something about Desiccant silica gel

Posted in General | 10:56

Desiccant silica gel has many different packing sizes. It can be conveniently put into the packing of various articles (for examples, instruments and gauges, electronical products, leathers, shoes, foodstuffs, medicines and household electric appliances, etc) in order to keep the articles from damp, mildew or rust corrosion. A microporous structure gives a very high surface area (800 square meters per gram). It is this structure that makes silica gel a high capacity desiccant. Water molecules adhere to the gels surface because it exhibits a lower vapour pressure than the surrounding air. When an equilibrium of equal pressure is reached, no more adsorption occurs. Fenglong Chemical Co., Ltd is a professional SILICA GEL supplier. Our silica gel manufacturing plant is located in Maanshan with manufacturing capacity of more than 500-MT silica gel per year.
