  2. Ethyl benzoate - Wikipedia

    en.wikipedia.org/wiki/Ethyl_benzoate

    Ethyl benzoate, C 9 H 10 O 2, is an ester formed by the condensation of benzoic acid and ethanol. It is a colorless liquid that is almost insoluble in water, but miscible with most organic solvents. As with many volatile esters, ethyl benzoate has a pleasant odor described as sweet, wintergreen, fruity, medicinal, cherry and grape. [1]

    en.wikipedia.org/wiki/PRL-8-53

    PRL-8-53 is a nootropic substituted phenethylamine that has been shown to act as a hypermnesic drug in humans; it was first synthesized by medical chemistry professor Nikolaus Hansl at Creighton University in the 1970s as part of his work on amino ethyl meta benzoic acid esters. [1] [2]

  4. 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.

    [3] [6] The first edition of the APA Publication Manual was published in 1952 as a 61-page supplement to the Psychological Bulletin, [7] [8] marking the beginning of a recognized "APA style". [3] The initial edition went through two revisions: one in 1957, and one in 1967. [3] Subsequent editions were released in 1974, 1983, 1994, 2001, 2009 ...

    While The Chicago Manual of Style focuses on providing guidelines for publishing, Turabian's A Manual for Writers of Research Papers, Theses, and Dissertations is intended for the creation and submission of academic works; where the two works differ "in small ways," Turabian's manual is designed to "better suit the requirements of academic ...

  7. Hammett equation - Wikipedia

    en.wikipedia.org/wiki/Hammett_equation

    The archetypal reaction is the alkaline hydrolysis of ethyl benzoate (R=R'=H) in a water/ethanol mixture at 30 °C. Measurement of the reaction rate k 0 combined with that of many substituted ethyl benzoates ultimately result in a reaction constant of +2.498.

  8. Sample preparation - Wikipedia

    en.wikipedia.org/wiki/Sample_preparation

    In analytical chemistry, sample preparation (working-up) refers to the ways in which a sample is treated prior to its analyses. Preparation is a very important step in most analytical techniques, because the techniques are often not responsive to the analyte in its in-situ form, or the results are distorted by interfering species .

  9. Diethylbenzenes - Wikipedia

    en.wikipedia.org/wiki/Diethylbenzenes

    Diethylbenzenes arise as side-products of the alkylation of benzene with ethylene, which can be described as two steps. The first step is the industrial route to ethylbenzene, which is produced on a large scale as a precursor to styrene.
