Moreover, Diisobutylaluminum Chloride is also known as diisobutylchloroaluminum, and bis(isobutyl
Solvent extraction of gold from leach liquors has been studied extensively using ion pair or solvent extractants e.g., dibutylcarbitol (diethyleneglycoldibutyl ether), 4-methyl-2-pentanone (methyl isobutyl
ketone; MIBK) and di (2-ethylhexyl) phosphoric acid (Akita et al., 1996).
Cobalt(II) chloride hexahydrate (98-102%; Alfa Aesar), imidazole (97 + %; Alfa Aesar), methyl isobutyl
ketone (EMSURE), dimethyl sulfoxide (Fisher), and diethyl ether (Fisher) were of ACS grade and used as received without further purification.
Bis(2-ethylhexyl) phosphoric acid (BEHPA) is an ion pairing compound used in extraction of basic compounds and alkyl chloroformates (such as isobutyl
chloroformate, IBCF) proved be a good derivatization reagents providing formation of N-alkoxycarbonyl esters .
Out of the 25 compounds, cytotoxic activity of the twenty compounds (A1-A20) was reported as a part of our study on isobutyl
The principal chemical ingredient was changed from isobutyl
nitrite to isopropyl nitrite after the former drug was found to be carcinogenic in 2006.
The BCF's most recent raw material prices survey for January 2017 show the three-monthly average prices for acetone going up 61 percent, n-butyl acetate up 40 percent and methyl isobutyl
ketone (MIBK) 20 percent.
Celanese Corporation (NYSE:CE) announced on Thursday a rise in the list and off-list selling prices for MIBK (methyl isobutyl
ketone) and MIBC (methyl isobutyl
carbinol) with effect from 1 February 2017, or as contracts allow.
Styrene (Sty), hexyl acrylate (HA), ethylhexyl acrylate (EHA), isooctyl acrylate (IOA), butyl acrylate (BA), and isobutyl
acrylate (IBA) reagents were purchased from Sigma-Aldrich and were used after inhibitor was removed by passing the monomers through a column of inhibitor remover (Sigma-Aldrich).
Then they tried distilled essence of chicken odour (isobutyl
butyrate, naphthalene, hexadecane and trans-limonene, if you must know), and that worked too.

To a cold solution of 2-amino thiazole (1a) (0.001 mol) in dry pyridine (15 mL) at 0-5 C the appropriate alkyl chloroformate (2a-d) (0.001 mol) namely, methyl chloroformate, ethyl chloroformate, propyl chloroformate and isobutyl
chloroformate was added.
