Benzoic acid, coal standard sample - (calorimeter consumables)

Product Name: Benzoic Acid
Molecular formula: C7H6O2
Molecular weight: 122.12
Introduction: It has a smell of benzene or formaldehyde and is flammable. Lightweight. No odor or slight odor similar to benzoin or benzaldehyde. It rapidly sublimates at 100 ℃ and can evaporate simultaneously with water vapor. Easily soluble in alcohols, chloroform, and ethers, soluble in benzene, carbon disulfide, turpentine, and oils, slightly soluble in water and petroleum ether
Purpose: Alkali quantification standard. Iodine quantification standard. Calorific value standard. Verify aluminum, boron, cerium, copper, iron, lead, manganese, mercury, nickel, nitrate, nitrite, silver, titanium, tungsten, and vanadium. Determine aluminum, copper, iron, titanium, and uranium. Organic microanalysis is a standard for determining carbon, hydrogen, oxygen, and relative molecular weight. It is also used in organic analysis for benzoylation. Used as a preservative.
