Usage

General Description

Isopropyl hydrogen sulphate, also known as isopropyl sulfate, is a chemical compound with the chemical formula (CH3)2CHOHSO4. It is an organosulfate compound that is often used as an intermediate in the production of various chemicals, including polymers and pharmaceuticals. Isopropyl hydrogen sulphate is a colorless, odorless liquid that is highly soluble in water and polar organic solvents. It is known to be a strong acid and can react violently with bases, causing severe burns upon contact with the skin or eyes. Due to its hazardous properties, proper precautions must be taken when handling isopropyl hydrogen sulphate, including the use of personal protective equipment and proper ventilation.

Cubane derivatives 1. Synthesis and molecular structures of the esters of 1,4-cubanedicarboxylic acid

An effective methods of esterification of 1,4-cubanedicarboxylic acid with alkylsulfuric acids is proposed.The derivatives of alkanols with substantially different pKa values are obtained in high yields.Molecular structures of the esters obtained are confirmed by various methods.The X-ray study showed a remarcable effect of the nature of an alkyl radical on the geometry of the cubane core. - Key words: 1,4-cubanedicarboxylic acid, esterification, alkylsulfuric acids, X-ray method.

SULFATION OF ALCOHOLS OF DIFFERENT STRUCTURES WITH CONCENTRATED SULFURIC ACID.

The authors report the results of a study of the applicability of these relationships to the whole series of aliphatic alcohols including industrial products. The concentration equilibrium constants of the reactions of these alcohols with 99. 5 mass % sulfuric acid are determined at 32. 5 degree , and it is shown that all the higher alcohols can be characterized by the same equilibrium constant, 3. 1 plus or minus 0. 5, which can therefore be recommended for practical calculations. The equilibrium constants were calculated from the rate constants of the forward and reverse reactions. It is shown that they depend on the relative basicities of sulfuric acid and monoalkyl sulfates.
