  2. Dichloromethane - Wikipedia

    en.wikipedia.org/wiki/Dichloromethane

    DCM is produced by treating either chloromethane or methane with chlorine gas at 400–500 °C. At these temperatures, both methane and chloromethane undergo a series of reactions producing progressively more chlorinated products.

  3. 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.

  4. Methyl group - Wikipedia

    en.wikipedia.org/wiki/Methyl_group

    The oxidation products derived from methyl are hydroxymethyl group −CH 2 OH, formyl group −CHO, and carboxyl group −COOH. For example, permanganate often converts a methyl group to a carboxyl (−COOH) group, e.g. the conversion of toluene to benzoic acid. Ultimately oxidation of methyl groups gives protons and carbon dioxide, as seen in ...

  5. A value - Wikipedia

    en.wikipedia.org/wiki/A_value

    In general, the larger a substituent's A-value, the larger the steric effect of that substituent. A methyl group has an A-value of 1.74 while tert-butyl group has an A-value of ~5. Because the A-value of tert-butyl is higher, tert-butyl has a larger steric effect than methyl. This difference in steric effects can be used to help predict ...

  6. Dichloroacetic acid - Wikipedia

    en.wikipedia.org/wiki/Dichloroacetic_acid

    Dichloroacetic acid (DCA), sometimes called bichloroacetic acid (BCA), is the organic compound with formula CHCl 2 CO 2 H.It is an analogue of acetic acid, in which 2 of the 3 hydrogen atoms of the methyl group have been replaced by chlorine atoms.

  7. tert-Butyldimethylsilyl chloride - Wikipedia

    en.wikipedia.org/wiki/Tert-Butyldimethylsilyl...

    It is commonly abbreviated as TBSCl or TBDMSCl. It is a chlorosilane containing two methyl groups and a tert-butyl group. As such it is more bulky that trimethylsilyl chloride. It is a colorless or white solid that is soluble in many organic solvents but reacts with water and alcohols.

  8. Methyldichlorophosphine - Wikipedia

    en.wikipedia.org/wiki/Methyldichlorophosphine

    Methyldichlorophosphine belongs to the group of halophosphines, some of which are used as intermediates in the production of plant protection agents, stabilizers for plastics, and catalysts. It is a precursor of the herbicide Glufosinate. It is also used in the production of flameproofing compounds. [4]

  9. Trimethylaluminium - Wikipedia

    en.wikipedia.org/wiki/Trimethylaluminium

    Tebbe's reagent, which is used for the methylenation of esters and ketones, is prepared from TMA and titanocene dichloride. [9] In combination with 20 to 100 mol % Cp 2 ZrCl 2 (zirconocene dichloride), the (CH 3) 2 Al-CH 3 adds "across" alkynes to give vinyl aluminium species that are useful in organic synthesis in a reaction known as ...
