Use | used in organic synthesis as an ethyl agent, used in the pharmaceutical industry to produce benzyl bromide, it is also used as an intermediate for light-sensitive materials. This product is the toughening agent of acetic acid fiber. used in organic synthesis, as an intermediate of ethylation reagent and photosensitive material, and also as a toughening agent of cellulose acetate used as a toughening agent of cellulose acetate ethylation reagent. Cellulose acetate toughening agent. It is used in the pharmaceutical industry to produce benzyl bromide and is also used as an intermediate for photosensitive materials. This product is the toughening agent of acetic acid fiber. |
production method | is obtained by esterification of p-Toluenesulfonyl chloride with ethanol. P-Toluenesulfonyl chloride was added to anhydrous ethanol and dissolved slightly with heat. Sodium hydroxide solution was slowly added dropwise at 10-12 °c, and the temperature was not more than 15 °c. The pH value was measured every half hour, and the reaction was maintained at 9.3-9.7 for 4 hours. Ice water was added and cooled to 0 °c, and crystals were precipitated. Filtration and drying gave ethyl p-toluenesulfonate. |
