Piperidine Derivatives with a Sulfur-Containing Function in the 4- Position1

Abstract: : The reaction of hydrogen sulfide with the gemdiol, 1-methyl-4-piperidone hydrochloride hydrate in isopropyl alcohol led to a good yield of a salt the properties of which showed it to be the desired 1-methyl-4, 4-dimercaptopiperidine hydrochloride (IV). The gem-dithiol IV was very reactive, for it was converted to the trithiolane on attempted recrystallization from alcohols and eliminated hydrogen sulfide on dissolution in water. A remarkable reaction was observed on treatment of the base 1-methyl-4-dimercaptopiperidine hydrate. The preparation of piperidines substituted in the 4-position with sulfur-containing functional groups requires an indirect route for synthesis. The most satisfactory preparation for 1-methyl-4-mercaptopiperidine has been shown to be through the gem-dithiol. (Author)

Separation of rare earths from other metal ions by anion exchange

Abstract: Elements of the rare earth group are retained by a nitrate-form anion exchange column from dilute nitric acid solutions in water-isopropyl alcohol. Elution with 1.5M nitric acid in 85% isopropyl alcohol allows many less sorbable elements to be separated from the rare earths. The higher rare earths can be eluted from the column using lower percentages of isopropyl alcohol and separated from bismuth(III), lead(II), and thorium(IV), which remain on the column. (auth)
