A method for identifying the optical activity of optical isomers

Abstract

The invention provides a method for identifying the optical rotation of an optical isocompound. The method comprises the steps of setting a spectrograph to be under specific spectral resolution based on a vibration spectrum technology, obtaining the absorbance of a sample under specific wave number, calculating characteristic values according to the characteristics of the specific wave number and an absorbance value, namely the spectroscopic characteristics of the sample, and whether the compound is a laevo isomer (L-type) or a dextroisomer (D-type) is judged. The method can achieve fast, simple, efficient and environmentally-friendly identification of the optical isocompound without light polarization attachments, the application range of a vibration spectrum is widened, and an important technical means is provided on the aspects of separation and purification, efficient production, safe use and the like of optical isocompounds.

Description

technical field

[0001] The invention relates to the field of food and drug safety, in particular to a method for identifying optical activity of optical isomer compounds. Background technique

[0002] Organic optical isomers belong to optical isomers in organic geometric isomers. Optical isomers mainly exist in organic matter, especially those containing sp 3 Hybridized carbon atoms in organic matter. When the carbon atom sp 3 When hybridized, its four outer electron orbitals are distributed in a tetrahedral three-dimensional manner. When the 4 outer electron orbitals of the above-mentioned carbon atoms are combined with different functional groups (A, B, C, D), it is called a chiral carbon atom (ie C * ), it produces optical isomers, and the structural schematic diagram is shown in the appendix of the specification figure 1 , where the thin line represents sp 3 Tetrahedral structure of hybridized carbon atoms, thick lines represent chiral carbon atoms (C * ) parallel...
