“Bitter” Results: Toward Sustainable Synthesis of the Most Bitter ...
网页2022年3月30日 · In this particular project, lidocaine was alkylated with benzyl chloride in the presence of a catalyst and subsequently subjected to an ion exchange reaction. This path resulted in the formation of two organic salts, denatonium benzoate and denatonium saccharinate, which are considered the most bitter substances currently known to mankind.
网页2021年9月20日 · denatonium benzoate and denatonium saccharinate, via an acid−base or ion exchange reaction conducted in ethanol. Moreover, for the first time, denatonium chloride and saccharinate were subjected to spectral analysis via various techniques (FTIR, UV, and NMR) and subsequently characterized …
Denatonium Benzoate - an overview | ScienceDirect Topics
网页Denatonium benzoate (Bitrex ®) has been used in the United States for over 20 years as an alcohol denaturant. In recent years, it has been heavily promoted for inclusion in household products, gardening products, and cosmetics to prevent accidental ingestions by children.
UV-VIS spectrophotometric method for the quantitation of all the ...
网页2006年2月1日 · We developed a method of deuterium labeling of denatonium benzoate (Bitrex) via H/D exchange of its α-carbon hydrogen atoms in CH2 group situated between carbonyl and quaternary ammonium groups.
UV–vis spectrophotometric method for the quantitation of all the ...
网页2006年1月15日 · The individual components of the general denaturant (denatonium benzoate, thiophene, methyl ethyl ketone and C.I. Reactive Red 24 dye) and a concentrated standard denaturing mixture (which requires a preliminary dilution with the proper volume of MEK prior to being used) have been kindly provided by the Customs Agency Chemical Laboratory in Rome.
Identification of transformation products of denatonium – Occurrence …
网页2019年10月10日 · The results can be explained by the low UV absorption of denatonium from the available UV irradiation of the sun at wavelengths above 290 nm (Fig. S5), which is the precondition of any direct photolysis. Others found a half-life of ≥235 days for the photodegradation of denatonium in water at pH 9.
Facile synthesis of deuterium-labeled denatonium cation and its ...
网页2015年6月16日 · We developed a method of deuterium labeling of denatonium benzoate (Bitrex) via H/D exchange of its α-carbon hydrogen atoms in CH2 group situated between carbonyl and quaternary ammonium groups. The proposed strategy is rapid, cost-efficient, and does not require derivatization reagents or further purification.
Direct Injection Gas Chromatographic/Mass ... - ACS Publications
网页1998年9月4日 · Direct injection GC/MS was investigated for the analysis of benzyldiethyl (2,6-xylylcarbamoylmethyl)ammonium benzoate (Bitrex), a quaternary ammonium salt, in various Canadian denatured alcohol formulations. Bitrex yielded predominantly a peak due to the neutral diethylamine derivative (I).
Denatonium - Wikipedia
网页Denatonium, usually available as denatonium benzoate (under trade names such as Denatrol, BITTERANT-b, BITTER+PLUS, Bitrex, Bitrix, and Aversion) and as denatonium saccharide (BITTERANT-s), is the most bitter chemical compound known, with bitterness thresholds of 0.05 ppm for the benzoate and 0.01 ppm for the saccharide. [ 1 ]
网页We de-veloped a method of deuterium labeling of denatonium ben-zoate (Bitrex) via H/D exchange of its α-carbon hydrogen atoms in CH2 group situated between carbonyl and quaternary ammonium groups. The proposed strategy is rapid, cost-effi-cient, and does not require derivatization reagents or further purification.
