Resorcinol (or resorcin) is a phenolic compound. It is an organic compound with the formula C 6 H 4 (OH) 2. It is one of three isomeric benzenediols, the 1,3-isomer (or meta-isomer). Resorcinol crystallizes from benzene as colorless needles that are readily soluble in water, alcohol, and ether, but insoluble in chloroform and carbon disulfide. [6]
Diglycidyl resorcinol ether, also called Resorcinol diglycidyl ether (RDGE) is a liquid aromatic organic chemical compound and chemically a glycidyl ether. [2] [3] The formula is C 12 H 14 O 4 [4] and the CAS Registry Number 101-90-6. [5] It is one of a number of glycidyl ethers available commercially that are used to reduce the viscosity of ...
1,3-Cyclohexanedione is produced by semi-hydrogenation of resorcinol: [3] [4] C 6 H 4 (OH) 2 + H 2 → C 6 H 8 O 2. 1,3-Cyclohexanedione exists in solution predominantly as the enol tautomer. Enolization of 1,3-cyclohexanedione.
Concrete has a very low coefficient of thermal expansion, and as it matures concrete shrinks. All concrete structures will crack to some extent, due to shrinkage and tension. Concrete which is subjected to long-duration forces is prone to creep. The density of concrete varies, but is around 2,400 kilograms per cubic metre (150 lb/cu ft). [1]
*** Benzene is a carcinogen (cancer-causing agent). *** Very flammable. The pure material, and any solutions containing it, constitute a fire risk. Safe handling: Benzene should NOT be used at all unless no safer alternatives are available. If benzene must be used in an experiment, it should be handled at all stages in a fume cupboard.
Azo violet (Magneson I; [1] p-nitrobenzeneazoresorcinol) is an azo compound with the chemical formula C 12 H 9 N 3 O 4.It is used commercially as a violet dye and experimentally as a pH indicator, appearing yellow below pH 11, and violet above pH 13. [2]
1,2,4-Trimethylbenzene, also known as pseudocumene, is an organic compound with the chemical formula C 6 H 3 (CH 3) 3.Classified as an aromatic hydrocarbon, it is a flammable colorless liquid with a strong odor.
