Product Detail

p-toluene sulfonic acid (Its molecular structural formula is p-CH3C6H4SO3H, also known as TsOH, English name is p-toluene sulfonic acid) referred to as PTS, is a non-oxidizing organic acid, white needle or powder crystals, soluble in water, alcohols, ethers and other polar solvents. Easy deliquescence, easy to make wood, cotton fabric dehydration and carbonization, insoluble in benzene and toluene. generating p-cresol when alkali fusion. Commonly, p-toluenesulfonic acid-monohydrate (TsOHH2O) or tetrahydrate (TsOH4H2O) is preferred. Preparation of methyl p-cresol acid in industry is by using concentrated sulfuric acid on the toluene sulfonation of p-toluenesulfonic acid. The preparated p-toluenesulfonic acid often contains benzene sulfonic acid and sulfuric acid impurities, can be purified in recrystallization of concentrated hydrochloric acid, azeotropic drying. p-toluene sulfonic acid is widely used as catalyst agent in the synthesis of pharmaceuticals, pesticides, polymerization stabilizer and organic synthesis (esters, etc.), paint intermediates and resin curing agent. And it is also the commonly used acid catalyst in organic synthesis. It is neutralized with sodium hydroxide and then obtains sodium p-toluene sulfonate, and react with phosphorus pentachloride, can obtains p-toluenesulfonyl chloride. The latter used in the nucleophilic substitution reaction, also used as alcohol hydroxyl protective group. p-CH3C6H4SO3Na + PCl5 →p-CH3C6H4SO2Cl. The use of p-toluenesulfonic acid also catalyzes the protection of dihydrofuran on the alcohol, carboxylic acid esterification, transesterification reaction, making the aldehyde generate acetal.

Reactivity Profile:

TOLUENE SULFONIC ACID, LIQUID, WITH MORE THAN 5% FREE SULFURIC ACID reacts exothermically with chemical bases (for example: amine, amides, and inorganic hydroxides). The reactions can generate dangerously large amounts of heat in small spaces. Dissolution in water or dilution of concentrated solutions with water may generate significant heat. Reacts with sodium hypochlorite to produce chlorine gas. Can react with active metals, including iron and aluminum, and also many less active metals, to dissolve the metal and liberate hydrogen and/or toxic gases. Can initiate possibly violent polymerization in certain alkenes such as allyl chloride. Reacts with cyanide salts and compounds to release gaseous hydrogen cyanide. Flammable and/or toxic gases are also often generated by reactions with dithiocarbamates, isocyanates, mercaptans, nitrides, nitriles, sulfides, and weak or strong reducing agents. Additional gas-generating reactions may occur with sulfites, nitrites, thiosulfates (to give H2S and SO3), dithionites (SO2), and carbonates: the carbon dioxide gas from the last is nontoxic but the heat and spattering from the reaction can be troublesome. Can catalyze (increase the rate of) chemical reactions. May burn but not ignited readily. Incompatible with carbides, bromates, chlorates, fulminates, picrates, and powdered metals [Haz. Chem. Data 1966]. Produces highly toxic fumes of oxides of sulfur when heated to decomposition.
