The distribution of gallium(b) and indium (b) between hydrochloric or sulphuric acid solution with sec-nonylphenoxy acetic acid(CA-100) in kerosene has been investigated under various conditions. CA-100 is a new organocarboxylic extractant, which has been shown to be efficient for gallium(b) and indium(b) where...

a facile one step synthesis of anilino alky1-n-substituted phthalimide i is reported. the following compounds belonging to this series were made: 1. (anilino-n-ethyl) phthalimide 8 2. (3,4, 5-trimethoxy anilino-n-ethyl) phthalimide 6 3. (3,4, 5-trimethoxy anilino-n-propyl) phthalimide 7 4. n-(ethyl phthalirnido-p-amino benzoyl) glutamic acid diethyl ester 10 5. n-(propyl phthalimido-p-amino ben...

A series of five-membered heterocyclic rings were synthesized by the reaction between benzoyl chloride and various chlolro-nitro-benzoyl chlorides and semi carbazide to form (C1-C7) compounds and was tested for their anti-inflammatory activity determined by rat-paw-oedema method. All the synthesis compounds have been characterized by 1HNMR, IR and Mass spectral data. The compounds were purified...

The transcriptional regulator CprK controls the expression of the reductive dehalogenase CprA in organohalide-respiring bacteria. Desulfitobacterium hafniense CprA catalyses the reductive dechlorination of the terminal electron acceptor o-chlorophenol acetic acid, generating the phenol acetic acid product. It has been shown that CprK has ability to distinguish between the chlorinated CprA subst...

To evaluate the contamination risk of the improper storage of pistachio nuts was studied in the major location of Saudi Arabia by studying the fungi associated with non and salted pistachio nuts. The infection with Aspergillus flavus and A. niger and treatment of this infection with some abiotic factors , salting and fumigation with acetic acid on the invasion and colonization were also studed....

(R)- and (S)-4-methyl-[1-3H,2-2H1]pentanal were prepared from L- and D-leucine via leucic acid and (S)- and (R)-4-methyl-[2-2H1]pentanoic acid. Decarbonylation of these samples with tris-(triphenylphosphine)rhodium chloride followed by Kuhn-Roth oxidation of the resulting 2-methylbutane gave chiral acetic acid of 35% e.e. S and 31% e.e. R configuration, respectively. The decarbonylation reactio...

background and objectives: acetic acid bacteria (aab) are useful in industrial production of vinegar. the present study aims at isolation and identification of acetic acid bacteria with characterization, optimization, and evaluation of their acetic acid productivity. materials and methods: samples from various fruits were screened for presence of acetic acid bacteria on glucose, yeast extract, ...

Sulfonic acid functionalized SBA-15 as a nanoporous acid catalyst was used in the synthesis of 2-Aryl benzoxazoles 4 by the condensation of 2-aminophenol 1 and benzoyl chlorides 2 under microwave irradiation in solvent free reaction conditions. The advantages of this methodology are good product yields (60-98%), being environmentally benign, short reaction times and easy work up.
