    en.wikipedia.org/wiki/Incipient_wetness_impregnation

    Incipient wetness impregnation (IW or IWI), also called capillary impregnation or dry impregnation, is a commonly used technique for the synthesis of heterogeneous catalysts. Typically, the active metal precursor is dissolved in an aqueous or organic solution. Then the metal-containing solution is added to a catalyst support containing the same ...

    en.wikipedia.org/wiki/Bis(trimethylsilyl)amine

    Bis(trimethylsilyl)amine (also known as hexamethyldisilazane and HMDS) is an organosilicon compound with the molecular formula [(CH 3) 3 Si] 2 NH. The molecule is a derivative of ammonia with trimethylsilyl groups in place of two hydrogen atoms.

  4. CRC Handbook of Chemistry and Physics - Wikipedia

    Mathematical Tables from Handbook of Chemistry and Physics was originally published as a supplement to the handbook up to the 9th edition (1952); afterwards, the 10th edition (1956) was published separately as CRC Standard Mathematical Tables. Earlier editions included sections such as "Antidotes of Poisons", "Rules for Naming Organic Compounds ...

    It also includes a table of physical constants, tables listing the properties of elementary particles, chemical elements, and nuclides, and information about conversion factors that are commonly used in physical chemistry. The most recent edition is the third edition (ISBN 978-0-85404-433-7), originally published by IUPAC in 2007. A second ...

  6. List of reagents - Wikipedia

    is an alkaline solution of potassium permanganate; used in organic chemistry as a qualitative test for the presence of unsaturation, such as double bonds; N-Bromosuccinimide: used in radical substitution and electrophilic addition reactions in organic chemistry. Also acts as a mild oxidizer to oxidize benzylic or allylic alcohols.

  7. Anhydrous - Wikipedia

    en.wikipedia.org/wiki/Anhydrous

    Organic solutions can be dried using a range of drying agents. Typically following a workup the organic extract is dried using magnesium sulfate or a similar drying agent to remove most remaining water. [5] Anhydrous acetic acid is known as glacial acetic acid.

  8. Trituration - Wikipedia

    en.wikipedia.org/wiki/Trituration

    In organic chemistry, trituration is a process used to purify crude chemical compounds containing soluble impurities. A solvent is chosen in which the desired product is insoluble and the undesired by-products are very soluble or vice versa. For example, when the impurities are soluble and the desired product is not, the crude material is ...

  9. Acid–base extraction - Wikipedia

    en.wikipedia.org/wiki/Acid–base_extraction

    Acid–base extraction is a subclass of liquid–liquid 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.
