The Basic Organic Chemistry industry is the foundation of Organic Chemistry. Its mission is to make a series of important Basic Organic Chemicals,or Organic Compound such as ethylene, propylene, butadiene, alcohol, aldehydes, ketones, carboxylic acids and their derivatives, halogens, epoxy compounds and nitrogen-containing Organic Chemicals, through various chemical processing methods, using the resources such as coal, oil, natural gas and biomass that exist in nature.
Organic Salt is the reactant between the Organic Acid (organic base) and other bases (or acid), which could be organic or inorganic. Generally Organic Salts are groups of organic matter combined with metal eg Sodium/Calcium/Potassium cations or non-metallic cations eg. NH4+. The most common Organic Salt Chemicals would be listed as Sodium Formate or sodium acetate etc.
Hot quality Benzenesulfonyl chloride CAS#98-09-9 Benzenesulfonyl chloride is a white flake crystal with a melting point of 69-71 °C, which is an important intermediate in organic synthesis of drugs, mainly used for the synthesis of amisulfonycin, chloramine-T, methyl sulfonyl mold and other drugs. The existing benzenesulfonyl chloride production process adopts the reaction of benzene and chlorosulfonic acid to prepare, due to the reaction of hydrogen chloride gas at a micro positive pressure into the plane absorption equipment, the water in the absorption equipment absorbs hydrogen chloride and is released

4) Application/Benzenesulfonyl chloride uses:
Benzenesulfonyl chloride reacts with Grignard reagents to form oxindoles from N-unsubstituted indoles. It is widely used to check the assay of thiamine in different food products. It is involved in the synthesis of alpha-disulfones, sulfonamides and sulfoante esters as precursor. It is a derivatization reagent for the determination of various amines in waste water and surface water at the sub-ppb level by gas chromatography-mass spectrometry. It is common reagent used in Hinsberg test for detection and distinguishing the type of amines as primary, secondary and tertiary amines.
