9,10-Dihydroanthracene is an organic compound that is derived from the polycyclic aromatic hydrocarbon anthracene. Several isomers of dihydroanthracene are known, but the 9,10 derivative is most common. It is a colourless solid that is used as a carrier of H 2 as a hydrogen-donor. [2]
Succinic anhydride hydrolyzes readily to give succinic acid: (CH 2 CO) 2 O + H 2 O → (CH 2 CO 2 H) 2. With alcohols (ROH), a similar reaction occurs, delivering the monoester: (CH 2 CO) 2 O + ROH → RO 2 CCH 2 CH 2 CO 2 H. Succinic anhydride is used in acylations under Friedel-Crafts conditions, as illustrated by the industrial route to the ...
9,10-Dihydroxyanthracene is an organic compound with the formula C 14 H 10 O 2.It is the hydroquinone form of 9,10-anthraquinone (AQ). It formed when AQ is hydrogenated. [1] It is easily dissolved in alkaline solutions and is often called soluble anthraquinone (SAQ).
Anthracene is a solid polycyclic aromatic hydrocarbon (PAH) of formula C 14 H 10, consisting of three fused benzene rings. It is a component of coal tar.Anthracene is used in the production of the red dye alizarin and other dyes, as a scintillator to detect high energy particles, as production of pharmaceutical drugs.
The patent describes the reaction of the alkenes with excess maleic anhydride at 200 °C in an autoclave. The excess alkene is removed by distillation in vacuo, the resulting alkenyl succinic anhydride hydrolyzed with dilute sodium hydroxide solution and the disodium salt reacted with an acid to achieve an alkenebutanedioic acid.
The unqualified term "dihydroxyanthraquinone" usually means a hydroxy derivative of 9,10-anthraquinone. The dihydroxy-9,10-anthraquinone functional group occurs widely in natural products, [3] [4] [5] and is an important feature of the anthracycline antitumour antibiotics. [6] [7] In particular, 1,8-Dihydroxy-9,10-anthraquinone is the precursor ...
There are several current industrial methods to produce 9,10-anthraquinone: The oxidation of anthracene. Chromium(VI) is the typical oxidant. The Friedel-Crafts reaction of benzene and phthalic anhydride in presence of AlCl 3. o-Benzoylbenzoic acid is an intermediate.
9,10-Dithioanthracene (DTA) is an organic molecule and a derivative of anthracene with two thiol groups. In 2004, DTA molecules were demonstrated to be able to "walk" in a straight line (reportedly a first [ citation needed ] ) on a metal surface by, in effect, mimicking the bipedal motion of a human being.
