p-Toluenesulfonic acid (PTSA, pTSA, or pTsOH) or tosylic acid (TsOH) is an organic compound with the formula CH 3 C 6 H 4 SO 3 H.It is a white extremely hygroscopic solid that is soluble in water, alcohols, and other polar organic solvents. [6]
Undecane (also known as hendecane) is a liquid alkane hydrocarbon with the chemical formula CH 3 (CH 2) 9 CH 3. It is used as a mild sex attractant for various types of moths and cockroaches, and an alert signal for a variety of ants. [3] It has 159 isomers. [4]
In the fossil fuel industries, hydrocarbon refers to naturally occurring petroleum, natural gas and coal, or their hydrocarbon derivatives and purified forms. Combustion of hydrocarbons is the main source of the world's energy. Petroleum is the dominant raw-material source for organic commodity chemicals such as solvents and polymers.
Pyrene is a polycyclic aromatic hydrocarbon (PAH) consisting of four fused benzene rings, resulting in a flat aromatic system. The chemical formula is C 16 H 10.This yellow-green solid is the smallest peri-fused PAH (one where the rings are fused through more than one face).
A ketone compound containing a carbonyl group (C=O) For organic chemistry, a carbonyl group is a functional group with the formula C=O, composed of a carbon atom double-bonded to an oxygen atom, and it is divalent at the C atom.
The toxic [11] relativistic metals (mercury, thallium, and lead) are preferred: inert counterions, such as the alkali metals, have only rarely led to reported success. [ 12 ] : 464 The Kochi reaction is a variation on the Hunsdiecker reaction developed by Jay Kochi that uses lead(IV) acetate and lithium chloride ( lithium bromide can also be ...
A hydrocarbon is any chemical compound that consists only of the elements carbon (C) and hydrogen (H). They all contain a carbon frame, and have hydrogen atoms attached to the frame. Often the term is used as a shortened form of the term aliphatic hydrocarbon. Most hydrocarbons are combustible. [2]
Bromine test is used to test the saturation of hydrocarbons. [17] The bromine test can also be used as an indication of the degree of unsaturation for unsaturated hydrocarbons. Bromine number is defined as gram of bromine able to react with 100g of product. [18] Similar as hydrogenation, the halogenation of bromine is also depend on the number ...
