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]
There are three structural isomers: 1,2-dihydroxybenzene (the ortho isomer) is commonly known as catechol, 1,3-dihydroxybenzene (the meta isomer) is commonly known as resorcinol, and 1,4-dihydroxybenzene (the para isomer) is commonly known as hydroquinone. [1]
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]
