Ethanol is receiving great interest as an alternative fuel. Methanol is another alcohol fuel that could serve as a replacement for gasoline. Although it is currently receiving much less attention, it has the potential to play an important role. Like ethanol, methanol also has the advantage of being a liquid fuel and it can be produced from gasification of a variety of feedstocks using well esta...

Background. Alcohol variants such as ethanol and methanol are simple organic compounds widely used in foods, pharmaceuticals, chemical synthesis, etc. Both are becoming an emerging health problem; abuse of ethanol containing beverages can lead to disparate health problems and methanol is highly toxic and unfit for consumption. Methods and Results. This review summarizes the basic knowledge abou...

Alcohols have been used as a fuel for engines since 19th century. Among the various alcohols, ethanol and methanol are known as the most suited renewable, bio-based and ecofriendly fuel for spark-ignition (SI) engines. The most attractive properties of ethanol and methanol as an SI engine fuel are that it can be produced from renewable energy sources such as sugar, cane, cassava, many types ...

In the present study antioxidant activity of the plant was assessed. For this purpose Cyperus rotundus was extracted by using different extraction solvents and evaluated for their antioxidant activity using different in vitro antioxidant assays. Total flavonoids contents in methanol extracts of Cyperus rotundus (8.15-18.25 mg CE/g of dry matter) were higher as compared to ethanol extracts (6.44...

Background: Nitric oxide (NO) is involved in numerous physiologic and phathophysiologic processes. Recently, further investigators have focused on serum NO determination. In our previous study, we validated a simple, cheap and rapid method for serum NO determination based on the Greiss reaction. Deproteinization is a necessary step for this reaction, thus, the present study was designed to asse...

BACKGROUND Methanol or ethylene glycol ingestion may result in significant morbidity or death without prompt treatment. Despite traditional and widespread use of intravenous ethanol as an antidote, its safety is not well described. An evaluation of the safety and ease of titrating ethanol infusions is necessary given the availability of an alternative antidote. OBJECTIVE To evaluate the safet...

In this study, transesterification of refined, bleached and deodorized (RBD) palm olein was carried out with methanol, ethanol and their mixtures at various methanol/ethanol ratios, while maintaining the molar ratio of oil to alcohol at 1:6. Potassium hydroxide was used as the catalyst. The process variables were temperature, methanol/ethanol molar ratio and amount of catalyst. The optimum biod...

In Bacillus subtilis, the fatty acid moiety of the phospholipids was affected differently during growth in the presence of 1.1 M-methanol or 0.7 M-ethanol, though at these concentrations methanol and ethanol had the same effects on growth rate and completely inhibited sporulation. Synthesis of phosphatidylglycerol was also strongly inhibited and the amount of total cell phospholipids was reduce...
