Pentyl propanoate (also known as amyl propionate) is an organic ester formed by the condensation of pentan-1-ol and propanoic acid. [2] It is a colorless liquid with an apple-like odor, that floats on water.
An ester of carboxylic acid.R stands for any group (organic or inorganic) and R′ stands for organyl group.. In chemistry, an ester is a compound derived from an acid (organic or inorganic) in which the hydrogen atom (H) of at least one acidic hydroxyl group (−OH) of that acid is replaced by an organyl group (−R).
Amyl nitrite is a chemical compound with the formula C 5 H 11 ONO. A variety of isomers are known, but they all feature an amyl group attached to the nitrite functional group. The alkyl group (the amyl in this case) is unreactive and the chemical and biological properties are mainly due to the nitrite group.
Lab notebook with the complete record of the experiments underlying a published paper. [1] Chemistry stencils that used to be used for drawing equipment in lab notebooks. A laboratory notebook (colloq. lab notebook or lab book) is a primary record of research.
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.
The sample came from the patch of windblown material called Rocknest, which had provided a sample previously for mineralogical analysis by CheMin instrument. [10] 3 December 2012: NASA reported SAM had detected water molecules, chlorine and sulphur. Hints of organic compounds couldn't be ruled out as contamination from Curiosity itself, however ...
The separation is facilitated by using amyl alcohol and centrifugation. The fat content is read directly via a special calibrated butyrometer. Gerber developed specialized butyrometers (tubes), pipettes, and centrifuges. Water baths built specifically for the Gerber tubes are often used.
Pentyl pentanoate (C 4 H 9 COOC 5 H 11) is an ester used in dilute solution to replicate the scent or flavour of apple, and sometimes pineapple. [1] It is referred to as pentyl valerate or amyl pentanoate using classical nomenclature. it can be used for a variety of chemical uses, such as in the production of flavoured products, like sweets.
