Dr. Thomas’ Eclectric Oil was a widely used pain relief remedy which was sold in Canada and the United States as a patent medicine from the 1850s into the early twentieth century. [ 1 ] [ 2 ] Like many patent medicines, it was advertised as a unique cure-all , but mostly contained common ingredients such as turpentine and camphor oil .
Joseph Thomas Clover (born 28 February 1825; baptised 7 May 1825 – 27 September 1882) [2] was an English doctor and innovator of anaesthesia.He invented a variety of pieces of apparatus to deliver anaesthetics, including ether and chloroform, safely and controllably.
In Canada, a wide range of basic laboratory reagents such as nitric acid and hydrogen peroxide are restricted as "explosives precursors". [37] Two of the main legal texts in Canada restricting the sale of certain chemicals are the Explosives Act, [ 38 ] and the Explosives Regulations, 2013 (SOR/2013-211). [ 39 ]
The chloroform molecule can be viewed as a methane molecule with three hydrogen atoms replaced with three chlorine atoms, leaving a single hydrogen atom. The name "chloroform" is a portmanteau of terchloride (tertiary chloride, a trichloride) and formyle, an obsolete name for the methylylidene radical (CH) derived from formic acid.
Structure and properties Index of refraction, n D: 1.4459 at 19 °C Abbe number? Dielectric constant, ε r: 4.8069 ε 0 at 20 °C : Bond strength? Bond length [1]: C-Cl 1.75 Å
Deuterated chloroform is a general purpose NMR solvent, as it is not very chemically reactive and unlikely to exchange its deuterium with its solute, [9] and its low boiling point allows for easy sample recovery. It, however, it is incompatible with strongly basic, nucleophilic, or reducing analytes, including many organometallic compounds.
