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

background: opioid abuse is common in iran. in recent years, methadone maintenance therapy (mmt) has gained popularity in this country. this study aimed at evaluation concurrent abuse of alcohol in patients under mmt. methods: a predesigned questionnaire was developed and completed after obtaining verbal consent among 49 subjects under mmt in kian rehabilitation centre during january 2014. resu...

Toxic alcohols that clinicians commonly encounter are ethylene glycol, methanol, and isopropanol. Adults ingest these either for suicidal intent or to achieve inebriation, since these substances are readily available and cheaper than alcohol. Nevertheless, assorted alcohols are used very often in many applications and any alcohol can be toxic if ingested in large enough quantities. Toxic alcoho...

 The catalytic air oxidation-trimerization of alcohols was carried out with hetropolyacids. In the presence of hetropolyacid formation of cyclotrimers of alcohols and aldol condensation products ...

In the present work, we compared chemical profile of organic compounds produced in non-catalytic pyrolysis sugarcane bagasse at 500 °C with those obtained by in-line catalytic upgrading vapor phase 350 °C. The influence over was evaluated testing two Ni-based catalysts employing an inert atmosphere (N2) and a reactive (H2) under atmospheric pressure yields liquid varying from 55 to 62%. Major c...

Background: dehydration fever is a common problem during the first week of life. This study aimed to compare the characteristics of neonates with fever due to dehydration and healthy infants. Methods: This cross-sectional study was performed on 324 neonates including 120 neonates with normal body temperature and 204 neonates with fever due to dehydration (hyperthermia) referred to Ghaem Hospit...

The purpose of this study was to investigate the effect of type of alcohols and humectants in inks formulation, and the papers surface morphology on the ink-jet printing properties. In order to investigate the influence of alcohol and humectant types on printing properties, the optimum ink formulation from previous study, which contained C.I. Reactive Blue 21 Ink2 was formulated with different ...

Self-association of alcohols; including ethanol, methanol, cyclopentanol and octanol in separate mixtures with inert solvents have been studied using FT-IR spectroscopy. Except for the band at 3640 cm–1 in the IR spectrum of the alcohols which is due to the monomer species, the presence of other bands in the region of stretching vibrational frequencies of OH (3100-3700 cm–1) are attributed to t...

Allitol, D-talitol and L-iditol are sugar alcohols that are rare in nature. Due to their previous rarity, little is known about the laxative effects of these rare sugar alcohols. Therefore, reliable data on the laxative effect that these sugar alcohols cause in experimental animals could help to evaluate the effectiveness of new monosaccharide laxative drugs. To investigate the laxative effect ...
