Sulphuric acid adsorbed on silica gel is a practical and useful catalyst for acetylation of varius alcohols, Phenols and amines.

Information on the stimulatory and inhibitory effects of cuticular alcohols on growth and virulence of insecticidal fungi is unavailable. Therefore, we set out to describe the content of cuticular and internal alcohols in the body of housefly larvae, pupae, males and females. The total cuticular alcohols in larvae, males and females of Musca domestica were detected in comparable amounts (4.59, ...

A convenient base-mediated strategy to synthesize 3-aryol-4-methyl (or benzyl)-2-methylthio furans 2 (trisubstituted furans) has been developed through the domino coupling/annulations between available α-oxo ketene dithioacetals 1 and propargyl alcohols. In this strategy, these types of bases play an important role in driving the domino coupling reaction of propargyl alcohols and further intram...

the present study has been designed to find out the protective effect of aqueus extract of terminalia arjuna against dehydration induced oxidative stress and uremia, protection by plant extract in male wister strain albino rats, and therefore to find out the scientific basis of local use of terminalia arjuna bark extract by village ayurved doctors to protect the progressive kidney disorder (ren...

The impact of feedstock impurities on catalytic process is among the crucial issues for processing real raw materials. A and model 92%-bioethanol contaminated with 0.03–0.3% mol 1-propanol or 2-propanol were used to make ethylene a proprietary alumina catalyst in isothermal flow reactor. We proposed formal kinetic describe impure bioethanol conversion byproducts it evaluate multi-tubular reacto...

Fourteen yeast strains from six genera were analysed for the presence of long-chain alcohols. Six strains from three genera contained long-chain alcohols, highest levels being found in Candida afbicans. The alcohols were identified and determined by TLC, GLC and GLC-MS. The major long-chain alcohols synthesized by these organisms were saturated, primary alcohols with C1 4, C I 6 or C18 chain le...

ALCOHOLS  The lower aliphatic alcohols are low to moderately toxic and usually have low vapor pressures, therefore inhalation toxicity is low.  Vapors may be an irritant to the eyes and mucous membranes.  Ingestion and absorption of the liquids through the skin can be a major health hazard.  Lower alcohols containing double or triple bonds exhibit a greater degree of toxicity and irritation...

Investigation of the mechanism of the NHC-initiated hydrosilylation of styryl alcohols in the presence of a dihydrosilane suggests a general base catalysis mechanism and not the activation of the dihydrosilane by the NHC.

  A male neonate from a 23 year-old mother by cesarean section without complication in labor or delivery had vomiting from birth for 9 days and lost 400 grams of body weight. He had severe dehydration upon admission to our hospital. After treating his dehydration and assessment of his problem by laboratory tests and radiography we found that he had esophageal atresia without hypoglycemia. We re...

tetrahydropyranylation of alcohols and phenols, acetylation of aldehydes and n-boc protection of amines are efficiently catalyzed by melamine trisulfonic acid (mtsa). all reactions were performed at room temperature in good to high yields.
