What are the effects of 4-Hydroxyisophthalic acid?

From a consideration of its structural similarity to salicylic acid, it was suggested at the Chemical Research Laboratory that 4-hydroxyisophthalic acid might also possess similar pharmacological prop

What are the advantages of ionic liquids?

Ionic liquids are odorless and non-flammable, and their vapor pressure is extremely low, so they can be used in high vacuum systems and can reduce environmental pollution caused by volatilization.

Separation and purification of ionic liquids

There have been a large number of reports in this regard, such as the use of ionic liquids to extract and recover butanol from fermentation broth; the use of supercritical CO2 to extract non-volatile

Preparation method of ionic liquid

​There are many types of ionic liquids. By changing the different combinations of cations and anions, different ionic liquids can be designed and synthesized. There are basically two basic methods for

Application of metal catalysts

​When selecting and designing metal catalysts, it is often considered that there should be appropriate energy adaptability and space adaptability between the metal component and the reactant molecules

Classification of metal catalysts

Refers to metal catalysts without a carrier, which can be divided into two types: single metal and alloy according to their composition. Usually used in the form of framework metal, metal wire mesh, m

Precautions for storage of 3-tert-butylphenol

​Store in a cool, ventilated warehouse. The storage temperature should not exceed 37°C. It should be stored separately from oxidants and edible chemicals, and avoid mixed storage.

The main use of stearic acid

Mainly used to produce stearates: sodium stearate, magnesium stearate, calcium stearate, lead stearate, aluminum stearate, cadmium stearate, iron stearate, potassium stearate.

Stearic acid properties and stability

Slightly soluble in cold water, soluble in alcohol and acetone, easily soluble in benzene, chloroform, ether, carbon tetrachloride, carbon disulfide, amyl acetate and toluene. Non-toxic.

Inspection method of stearic acid
