Dibenzothiophene (DBT, diphenylene sulfide) is the organosulfur compound consisting of two benzene rings fused to a central thiophene ring. It has the chemical formula C 12 H 8 S. It is a colourless solid that is chemically somewhat similar to anthracene .
In the minor reaction pathway, a Prilezhaev epoxidation [14] results in the formation of thiophene-2,3-epoxide that rapidly rearranges to the isomer thiophene-2-one. [12] Trapping experiments [ 15 ] demonstrate that this pathway is not a side reaction from the S -oxide intermediate, while isotopic labeling with deuterium confirm that a 1,2 ...
Dibenzofuran is a relatively non-toxic compound as evidenced by rats being unaffected after a 200-day diet consisting of 0.025 – 0.4% of DBF. [1] The polychlorinated dibenzofurans are however among the potentially toxic dioxins and dioxin-like compounds.
Benzenesulfonic acid (conjugate base benzenesulfonate) is an organosulfur compound with the formula C 6 H 6 O 3 S.It is the simplest aromatic sulfonic acid.It forms white deliquescent sheet crystals or a white waxy solid that is soluble in water and ethanol, slightly soluble in benzene and insoluble in nonpolar solvents like diethyl ether.
Disulfiram-alcohol reaction (DAR) is the effect of the interaction in the human body of alcohol drunk with disulfiram or some types of mushrooms. [ 1 ] [ 2 ] The DAR is key to disulfiram therapy that is widely used for alcohol-aversive treatment and management of other addictions (e.g. cocaine [ 3 ] [ 4 ] use).
Octyldodecanol is a branched-chain primary alcohol used as the isomer 2-octyl-1-dodecanol in cosmetics such as lipstick, [2] or as an anti-blooming agent in facepowder. [3] It is a medium spreading emollient, with equilibrium spreading pressure of 17.0 dyne/cm. [4] Octyldodecanol is in the class of Guerbet alcohols, because it has the branch at the β position. [5]

reaction of methacrylic acid with ethylene oxide; esterification of methacrylic acid with a large excess of ethylene glycol. Both these methods give also some amount of ethylene glycol dimethacrylate. During polymerization of hydroxyethylmethacrylate, it works as crosslinking agent. [5]
