  2. Acetonitrile - Wikipedia

    en.wikipedia.org/wiki/Acetonitrile

    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.

    en.wikipedia.org/wiki/Certificate_of_analysis

    A certificate of analysis (COA) is a formal laboratory-prepared document that details the results of (and sometimes the specifications and analytical methods for) one or more laboratory analyses, signed—manually or electronically—by an authorized representative of the entity conducting the analyses. This document gives assurances to the ...

  6. Azeotrope tables - Wikipedia

    en.wikipedia.org/wiki/Azeotrope_tables

    This page contains tables of azeotrope data for various binary and ternary mixtures of solvents. The data include the composition of a mixture by weight (in binary azeotropes, when only one fraction is given, it is the fraction of the second component), the boiling point (b.p.) of a component, the boiling point of a mixture, and the specific gravity of the mixture.

    en.wikipedia.org/wiki/Tetrakis(acetonitrile...

    Tetrakis(acetonitrile)copper(I) tetrafluoroborate can be prepared starting from nitrosyl tetrafluoroborate, which is obtained from dinitrogen tetroxide and tetrafluoroboric acid. The nitrosyl salt is then reacted with metallic copper in acetonitrile, initially producing a green-blue copper(II) complex. This complex is reduced to the copper(I ...

  9. Di-tert-butyl dicarbonate - Wikipedia

    en.wikipedia.org/wiki/Di-tert-butyl_dicarbonate

    The first step in this reaction sequence is the formation of the carbamate from the reaction of the amide nitrogen with boc anhydride in acetonitrile using DMAP as a catalyst. Di-tert-butyl dicarbonate also finds applications as a polymer blowing agent due to its decomposition into gaseous products upon heating. [15] [16]
