  2. Benzyl chloride - Wikipedia

    en.wikipedia.org/wiki/Benzyl_chloride

    Benzoic acid (C 6 H 5 COOH) can be prepared by oxidation of benzyl chloride in the presence of alkaline KMnO 4: C 6 H 5 CH 2 Cl + 2 KOH + 2 [O] → C 6 H 5 COOK + KCl + H 2 O. Benzyl chloride may be used in the synthesis of amphetamine-class drugs, and for this reason, sales of benzyl chloride are monitored as a List II drug precursor chemical ...

  3. Chlorotoluene - Wikipedia

    en.wikipedia.org/wiki/Chlorotoluene

    These compounds are diazotized followed by treatment with cuprous chloride. [1] Industrially, the diazonium method is reserved for 3-chlorotoluene. The industrial route to 2- and 4-chlorotoluene entails direct reaction of toluene with chlorine. The more valuable 4-chlorotoluene is separated from 2-chlorotoluene by distillation.

  4. Liquid–liquid extraction - Wikipedia

    en.wikipedia.org/wiki/Liquidliquid_extraction

    A separatory funnel used for liquidliquid extraction, as evident by the two immiscible liquids.. Liquidliquid extraction, also known as solvent extraction and partitioning, is a method to separate compounds or metal complexes, based on their relative solubilities in two different immiscible liquids, usually water (polar) and an organic solvent (non-polar).

  5. Benzaldehyde - Wikipedia

    en.wikipedia.org/wiki/Benzaldehyde

    Amygdalin 2 H 2 O HCN benzaldehyde 2 × glucose 2 × Benzaldehyde contributes to the scent of oyster mushrooms (Pleurotus ostreatus). Reactions Benzaldehyde is easily oxidized to benzoic acid in air at room temperature, causing a common impurity in laboratory samples. Since the boiling point of benzoic acid is much higher than that of benzaldehyde, it may be purified by distillation. Benzyl ...

  6. Benzal chloride - Wikipedia

    en.wikipedia.org/wiki/Benzal_chloride

    Benzal chloride is an organic compound with the formula C 6 H 5 CHCl 2. [1] This colourless liquid is a lachrymator and is used as a building block in organic synthesis . Preparation and usage

  7. Acid–base extraction - Wikipedia

    en.wikipedia.org/wiki/Acid–base_extraction

    Acid–base extraction is a subclass of liquidliquid extractions and involves the separation of chemical species from other acidic or basic compounds. [1] It is typically performed during the work-up step following a chemical synthesis to purify crude compounds [2] and results in the product being largely free of acidic or basic impurities.

  8. Menshutkin reaction - Wikipedia

    en.wikipedia.org/wiki/Menshutkin_reaction

    The reaction is the method of choice for the preparation of quaternary ammonium salts. [1] Some phase transfer catalysts (PTC) can be prepared according to the Menshutkin reaction, for instance the synthesis of triethyl benzyl ammonium chloride (TEBA) from triethylamine and benzyl chloride :

  9. Photochlorination - Wikipedia

    en.wikipedia.org/wiki/Photochlorination

    Benzyl chloride can also be converted via benzyl cyanide with subsequent hydrolysis into phenylacetic acid. [22] [23] The disubstituted benzal chloride is converted to benzaldehyde, a popular flavorant [24] and intermediate for the production of malachite green and other dyes. [25] The trisubstituted benzotrichloride is used for the hydrolysis ...
