Potassium hydrogen terephthalate - Introduction
Potassium hydrogen phthalate is a white crystalline solid with the chemical formula C8H5KO4 and a molecular weight of 204.22g/mol. The following is a description of its nature, use, preparation and safety information:
Nature:
-Potassium hydrogen phthalate is a white crystal under normal temperature and pressure, soluble in water and some organic solvents.
-It is an acidic substance that can react with alkali to form phthalate.
-Potassium hydrogen phthalate has certain stability, but it will decompose under high temperature or humid conditions.
Use:
-Potassium hydrogen phthalate is an important chemical raw material, which is widely used in synthetic dyes, pigments, medicine and food industries.
-It can be used to prepare Ester polymers, rubbers and resins.
-Potassium hydrogen phthalate is also used as an emulsifier, buffer and chelating agent.
Preparation Method:
-Potassium hydrogen phthalate can be obtained by reacting phthalic acid with potassium hydroxide.
-First dissolve the phthalic acid in water, and then add an appropriate amount of potassium hydroxide solution to make the reaction proceed.
-Filtration and crystallization can obtain potassium hydrogen phthalate with higher purity.
Safety Information:
-Potassium hydrogen phthalate is irritating to the eyes and skin and should be avoided when in contact with it.
-Wear appropriate personal protective equipment, including goggles and gloves.
-avoid inhalation of its dust or mist, should be in a well-ventilated place of operation.
-If you feel unwell after inhalation or contact, you should seek medical advice immediately.
