Carbinol tris

M-CAPROIC ANHYDRIDE, 21, 13 Capronitrile, 26, 33 Caproylchlororesorcinol, 20, 58 o-Caproylphenol, 20, 58 -Caproylphenol, 20, 58 Caproylresorcinol, 20, 58 w-Carbethoxypelargonyl chloride, 25, 21 5-Carbethoxyvaleiyl chloride, 25, 21 CARBINOL, TRIPHENYL-, 23, 98 Carbinol, tris-(4-phenylphenyl)-,... [Pg.101]

Auf ahnliche Weise wird Tris-[2,6-dimethoxy-phenyl]-methan (95% d. Th.) aus dem entsprechenden Carbinol erhalten1. [Pg.412]

Asymmetric addition of Grignard reagents to CJfflHO.1 Grignard reagents pretreated with (-)-l at -78° add to benzaldehyde with only slight enantiose-lectivity ( 20% ee). But if the addition is effected in the presence of 2,4,6-tri-methylphenoxyaluminum dichloride (2), the carbinol is obtained in 40-70% ee. [Pg.48]

Wien a little concentrated hydrochloric acid is added the green solution becomes yellow, because now the trichloride is formed and the influence of the second benzene ring is also suppressed, so that the (yellow) fuchsonimine type is formed. All triphenylmethane dyes dissolve in concentrated sulphuric acid with an orange-yellow colour exactly like triphenylcarbinol itself (carbonium salts, Kehrmann). By diluting the solution with water a colourless solution of the tri-acid benzenoid carbinol salt can be obtained. [Pg.330]

In complete accordance with Willstatter s theory, fuchsone is only yellowish-orange in colour. But if, in addition, one of the two free benzene rings has an OH-group in the p-position, we have the dye benzaurin already mentioned on p. 328. The o-carboxylic acid of this dye is the quinonoid form of phenolphthalein. In fact, the colour tones of these two substances are very similar. Phenolphthalein is decolorised by concentrated alkali NaOH (KOH) is added on and the trisodium (or potassium) salt of the benzenoid carbinol form is produced. (Try these reactions with phenolphthalein.)... [Pg.332]

Di-n-butyl ketone n-Butyl bromide Tri-n-butyl carbinol 91... [Pg.12]

Solvent extraction by tributyl phosphate (TBP) (13, 96), dithizone (20, 71, 72), cupferron (89), thenoyl trifluoroacetone (TTA) (55), diiso-propyl ketone (26), mesityl oxide (92), tri-n-benzylamine and methyl di-n-octylamine (99), diisopropyl and diisobutyl carbinol (100) have all found some application on the trace scale. Acetylaeetone and methyl isobutyl ketone extract milligram amounts of polonium almost quantitatively from hydrochloric acid, but the stable polonium-organic compounds which are formed make it difficult to recover the polonium in a useful form from solutions in these ketones (7). Ion exchange (22, 115, 119) and paper chromatography (44, 87) have also been used for trace scale separations of polonium, but the effects of the intense alpha-radiation on organic com-... [Pg.202]
