Acetonitrile is used mainly as a solvent in the purification of butadiene in refineries. Specifically, acetonitrile is fed into the top of a distillation column filled with hydrocarbons including butadiene, and as the acetonitrile falls down through the column, it absorbs the butadiene which is then sent from the bottom of the tower to a second separating tower.
An online version of The Merck Index, including historic records and new updates not in the print edition, [1] is commonly available through research libraries. It also includes an appendix with monographs on organic named reactions. The 15th edition was published in April 2013. Monographs in The Merck Index typically contain: [1] a CAS ...
Bis(acetonitrile)palladium dichloride is the coordination complex with the formula PdCl 2 (NCCH 3) 2. It is the adduct of two acetonitrile ligands with palladium(II) chloride. It is a yellow-brown solid that is soluble in organic solvents. The compound is a reagent and a catalyst for reactions that require soluble Pd(II). [1]
A colorless liquid, it is derived from acetonitrile (CH 3 CN) by replacement of one H with Cl. In practice, it is produced by dehydration of chloroacetamide. [1] The compound is an alkylating agent, [2] and as such is handled cautiously. Chloroacetonitrile is also generated in situ by the reaction of acetonitrile with sulfur monochloride.
Screenshot of the CAS Common Chemistry database with information about caffeine ().. A CAS Registry Number [1] (also referred to as CAS RN [2] or informally CAS Number) is a unique identification number, assigned by the Chemical Abstracts Service (CAS) in the US to every chemical substance described in the open scientific literature, in order to index the substance in the CAS Registry.
The cation was first reported in 1923 with a nitrate anion as a byproduct of the reduction of silver nitrate with a suspension of copper powder in acetonitrile. [4] [Cu(CH 3 CN) 4]PF 6 is generally produced by the addition of HPF 6 to a suspension of copper(I) oxide in acetonitrile: [5] Cu 2 O + 2 HPF 6 + 8 CH 3 CN → 2 [Cu(CH 3 CN) 4]PF 6 + H 2 O
Trichloroacetonitrile can be obtained by chlorination of acetonitrile on a zinc, copper and alkaline earth metal halide-impregnated activated carbon catalyst at 200–400 °C with a 54% yield. [ 3 ] The high temperatures required by this process favours the formation of byproducts, such as tetrachloromethane .
