Diisobutyl carbinol

A/B = alkylated ben2enes TBU = tetrabutyl urea TOP = trioctyl phosphate and DIBC = diisobutyl carbinol. See text. 

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-...

The oxidation of various alcohols by the poly(e-carbobenzoxy-L-lysine)-Cu complex was studied by Welch et aL127. The polymer catalyst showed selectivity in oxidation by virtually excluding alcohols of bulky structure such as diisopropyl and diisobutyl carbinol while admitting simple alcohols arch as n-butyl, iso-butyl, and sec-butyl. It was suggested from structural studies that the selectivity of the polymer catalyst resulted from the highly complex geometry of the molecular cage formed by the helix and the amino acid side chain around the coordinated Cu. The... 

The alkylated anthraquinone process accounts for over 95% of the world production of H202, mainly because the it operates under mild conditions and direct contact of 02 and H2 is avoided. In this process, 2-alkylanthraquinone (the alkyl group is typically an ethyl, terf-butyl or amyl group) is dissolved in a mixture of a non-polar solvent (C9-Cn alkylbenzene) and a polar solvent [Trioctyl phosphate (TOP), or tetrabutyl urea (TBU) or diisobutyl carbinol (DIBC)] and then hydrogenated over a precious metal (Pd or Ni) catalyst in a three-phase reactor (trickle bed or slurry bubble column) under mild reaction conditions (<5bar, <80 °C) to generate 2-alkylanthrahydroquinone [1-3, 5], The latter is then auto-oxidized with air in a... 

Copper on a synthetic polypeptide demonstrated a remarkable selectivity in alcohol dehydrogenation by virtually excluding alcohols of complex structure such as diisopropyl and diisobutyl carbinol, while admitting simple alcohols such as n-butyl, isobutyl and sec-butyl 129). 

The proximity in the Db behavior in the TiOA experiments to that of Pa was the reason for performing a series of extractions of Db into diisobutyl-carbinol (DIBC), a secondary alcohol which is a very specific extractant for Pa. The extraction from concentrated HBr solution in ARC A II was followed by the elution of a Nb fraction in 6 M HC1/0.0002 M HF, and of a Pa fraction in 0.5 M HC1. The number of 262Db decays observed in the Nb fraction indicated that less than 45% of the Db was extracted into DIBC, and the extraction sequence Db < Nb < Pa was established [46]. This suggests that the seeming similarity between Db and Pa concluded from the TiOA experiments is not a general phenomenon.
