saponify การใช้

• One equivalent of sodium hydroxide will saponify the 2-ester selectively.
• The crude annulation product is treated with 10 % potassium hydroxide in methanol to saponify the ester side product formed from the reaction of the phenolic product with excess vinylketene ( Scheme 6 ) . center
• Calcium metal is found in some drain cleaners, where it functions to generate heat and calcium hydroxide that saponifies the fats and liquefies the proteins ( e . g ., hair ) that block drains.
• Potassium hydroxide is a strong base, which is used in industry to neutralize strong and weak acids, to control pH and to manufacture potassium saponify fats and oils, in industrial cleaners, and in hydrolysis reactions, for example of esters.
• Alkali burns, on the other hand, such as those resulting from exposure to ammonium hydroxide or ammonium chloride or other chemicals with a pH above 11.5, will cause cellular tissue in the sclera to saponify and should be considered medical emergencies requiring immediate treatment.
