Samuel Guthrie was born in Brimfield, in Hampden's county, Massachusetts, in 1782 [1] "Dr. Guthrie was of dark complexion, medium stature, slender build, slightly stooping figure, and thoughtful mien; his head was well-formed and of full medium size, features slightly oval, nose prominent and a little irregular in shape."
Part 20 of the latter restricts the sale, acquisition, and storage of ten explosives precursors, namely, ammonium nitrate in solid form and with a nitrogen concentration >=28%, hydrogen peroxide >=30% conc., nitromethane, potassium chlorate, potassium perchlorate, solid sodium chlorate, nitric acid >= 75% conc., potassium nitrate, mixtures of ...
Chloroform, [10] or trichloromethane (often abbreviated as TCM), is an organochloride with the formula C H Cl 3 and a common solvent.It is a volatile, colorless, sweet-smelling, dense liquid produced on a large scale as a precursor to refrigerants and PTFE. [11]
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, also known as chloroform-d, is the organic compound with the formula CDCl 3. Deuterated chloroform is a common solvent used in NMR spectroscopy. [2] The properties of CDCl 3 and ordinary CHCl 3 are virtually identical. Deuterochloroform was first made in 1935 during the years of research on deuterium. [3]
Chlorodyne sold extremely well for many years; as its active ingredients were well known, local chemists' shops would also make up cheaper generic versions for sale to their customers. Here is an example of such a generic formulation, from Materia Medica by William Hale-White & A.H. Douthwaite, 21st edition (1932):
Sir James Young Simpson, 1st Baronet FRSE FRCPE FSA Scot (7 June 1811 – 6 May 1870) was a Scottish obstetrician and a significant figure in the history of medicine.He was the first physician to demonstrate the anaesthetic properties of chloroform in humans and helped to popularize its use in medicine.
Bromoform was discovered in 1832 by Löwig who distilled a mixture of bromal and potassium hydroxide, as analogous to preparation of chloroform from chloral. [5]Bromoform can be prepared by the haloform reaction using acetone and sodium hypobromite, by the electrolysis of potassium bromide in ethanol, or by treating chloroform with aluminium bromide.
