  2. IUPAC nomenclature of organic chemistry - Wikipedia

    en.wikipedia.org/wiki/IUPAC_nomenclature_of...

    If there are multiple functional groups of the same type, either prefixed or suffixed, the position numbers are ordered numerically (thus ethane-1,2-diol, not ethane-2,1-diol.) The N position indicator for amines and amides comes before "1", e.g., CH 3 CH(CH 3)CH 2 NH(CH 3) is N,2-dimethylpropanamine.

  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. Organosulfate - Wikipedia

    en.wikipedia.org/wiki/Organosulfate

    The SO 4 core is a sulfate group and the R group is any organic residue. All organosulfates are formally esters derived from alcohols and sulfuric acid (H 2 SO 4) although many are not prepared in this way. Many sulfate esters are used in detergents, and some are useful reagents.

  5. Ethyl sulfate - Wikipedia

    en.wikipedia.org/wiki/Ethyl_sulfate

    Ethyl sulfate can be produced in a laboratory setting by reacting ethanol with sulfuric acid under a gentle boil, while keeping the reaction below 140 °C. The sulfuric acid must be added dropwise or the reaction must be actively cooled because the reaction itself is highly exothermic.

  6. Alkyl group - Wikipedia

    en.wikipedia.org/wiki/Alkyl_group

    In organic chemistry, an alkyl group is an alkane missing one hydrogen. [1] The term alkyl is intentionally unspecific to include many possible substitutions. An acyclic alkyl has the general formula of −C n H 2n+1. A cycloalkyl group is derived from a cycloalkane by removal of a hydrogen atom from a ring and has the general formula −C n H ...

  7. 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 ...

    The chemical structure of 1-butyl-3-methylimidazolium hexafluorophosphate ([BMIM]PF 6), a common ionic liquid. Proposed structure of an imidazolium-based ionic liquid. An ionic liquid (IL) is a salt in the liquid state at ambient conditions.
