[1] [2] In physical and analytical chemistry, infrared spectroscopy (IR spectroscopy) is a technique used to identify chemical compounds based on the way infrared radiation is absorbed by the compound. The absorptions in this range do not apply only to bonds in organic molecules.
Isopropyl acetate is a solvent with a wide variety of manufacturing uses that is miscible with most other organic solvents, and slightly soluble in water (although less so than ethyl acetate). It is used as a solvent for cellulose, plastics, oil and fats. It is a component of some printing inks [4] and perfumes.
Isopropenyl acetate is an organic compound, which is the acetate ester of the enol tautomer of acetone. This colorless liquid is significant commercially as the principal precursor to acetylacetone .
In situ infrared spectroscopy may be used to monitor the course of a reaction, provided a reagent or product shows distinctive absorbance in the IR spectral region. The rate of reactant consumption and/or product formation may be abstracted from the change of absorbance over time (by application of Beers' Law ).

IRPD spectroscopy has been shown to use electron ionization, corona discharge, and electrospray ionization to obtain spectra of volatile and nonvolatile compounds. [2] [3] Ionized gases trapped in a mass spectrometer can be studied without the need of a solvent as in infrared spectroscopy. [4] Schematic diagram of infrared photodissociation ...
Infrared spectroscopy (IR spectroscopy or vibrational spectroscopy) is the measurement of the interaction of infrared radiation with matter by absorption, emission, or reflection. It is used to study and identify chemical substances or functional groups in solid, liquid, or gaseous forms. It can be used to characterize new materials or identify ...
Isopropylamine can be obtained by reaction of isopropyl alcohol with ammonia in presence of a catalyst: [3] (CH 3) 2 CHOH + NH 3 → (CH 3) 2 CHNH 2 + H 2 O. Isopropylamine is a building block for the preparation of many herbicides and pesticides including atrazine, bentazon, glyphosate, imazapyr, ametryne, desmetryn, prometryn, pramitol, dipropetryn, propazine, fenamiphos, and iprodione.
