In a series of publications which have appeared during the last five years (1-8), the activity of certain organic compounds, particularly propylene and triethylene glycols, in killing air-borne bacteria and viruses has been described. The types of microorganisms found to be susceptible and some effects on this killing action of changes in the temperature, relative humidity, and concentration of...

Humanity’s growing dependence on non-renewable resources and the ensuing environmental impact thus generated have spurred search for alternatives to replace chemicals energy obtained from petroleum derivatives. Within group of biofuels, biodiesel has managed expand worldwide at considerable levels, going 20 million tn/year in 2010 47 2022, boosting supply glycerol, a by-product its synthesis th...

The synthesis of propylene oxide from propylene glycol, a derivative of bio-glycerol, was firstly realized in the presence of alkali-loaded silica catalysts to achieve 44% conversion and 70% selectivity.

An experimental and theoretical study was undertaken for three ether glycols (mixtures of isomers). The present paper, being the first part a complex study, reports using static apparatus, namely, vapor–liquid equilibria dipropylene glycol methyl (DPM), n-butyl (DPnB), propylene (PnB), their pseudo-binary mixtures composed (PnB + DPM), (DPM DPnB), aqueous solutions each ether. explored temperat...

Lipids have wide range of applications in food and pharmaceuticals. The pharmaceuticals application lipid is to improve solubility drug also helps the bioavailability. dissolution/dissolving phase, which probably rate-limiting component for oral absorption poorly water-soluble drugs, eliminated by pre-dissolving lipids, surfactants, or combinations excipients surfactants. most widely used co-so...

A double-blind crossover comparison of efficacy and recovery from midazolam 5 mg and diazepam (in propylene glycol) 10 mg was undertaken in eight volunteer subjects. It was found that midazolam was significantly more potent in this dose ratio than diazepam, helping to explain the finding of previous studies that the recovery from midazolam and diazepam in a 1:2 dose ratio is comparable.

M etabolic acidosis is a common acid-base disturbance in hospitalized patients. Distinguishing anion gap from non–anion gap metabolic acidosis is a very helpful exercise and enables the clinician to narrow the etiology of the particular acidosis. The use of the anion gap was popularized in an article by Emmett and Narins (1). Over the past few years, the list of conditions that can cause an ani...

A simple, rapid, and reliable method was developed for the quantitative determination of diethylene glycol (DEG) in pharmaceutical products using capillary gas chromatography with flame ionization detection. The method uses ethylene glycol as internal standard and allows for the separation of propylene glycol and DEG. The assay was linear in a DEG concentration range between 1.0 and 10.00 mg/mL...
