Additionally, Isophthaloyl Chloride, Terephthaloyl Chloride, 2-ethyl hexanoyl Chloride, Isobutyryl Chloride and Pivaloyl Chloride are expected to maintain their dominance in the export market.
Solar Friedel-Crafts acylation of benzene with isobutyryl chloride.
The acylation of benzene with isobutyryl chloride was attempted using this solar heat source.

2), their aqueous solubility was lower than that of isobutyryl thiocholine as shown in Table 2.
The reactivity of isobutyryl and cyclohexanecarboxyl compounds with acetylcholinesterase was negligible (almost equal to their rate of self-hydrolysis), demonstrating that these substrates are specific to serum cholinesterase.
As for the difference between the sensitivity and the specificity of the test (<17%), we found that variability in the acylcarnitine values was responsible for >85% of "false flagging." In particular, propionylcarnitine and butyryl (or isobutyryl)carnitine ratios just above the respective cutoff values were responsible for ~25% of the falsely flagged samples, whereas in reality these minor increases are of no pathological significance.
