The carbonylation of methanol with carbon monoxide to methyl formate (methyl methanoate) is catalyzed by strong bases, such as potassium methoxide. [ 7 ] [ 8 ] The main application of potassium methoxide is use as basic transesterification catalyst in biodiesel synthesis (as a 25-32% methanolic solution).
Methanol fuel is an alternative biofuel for internal combustion and other engines, either in combination with gasoline or independently. Methanol (CH 3 OH) is less expensive to sustainably produce than ethanol fuel, although it is more toxic than ethanol and has a lower energy density than gasoline.
Methanol and its vapours are flammable. Moderately toxic for small animals – Highly toxic to large animals and humans (in high concentrations) – May be fatal/lethal or cause blindness and damage to the liver, kidneys, and heart if swallowed – Toxicity effects from repeated over exposure have an accumulative effect on the central nervous system, especially the optic nerve – Symptoms may ...
Stock tanks can be repurposed as backyard pools, or "stock tank pools," using chlorine tabs and a filter pump. Stock tanks are increasingly used as "rustic" backyard above-ground pools, or "stock tank pools" by retrofitting a filter pump [4] and adding chlorine or stabilized hydrogen peroxide [5] to keep the water clean throughout the summer.

When methanol and carbon monoxide are combined in the presence of a strong base, the result is methyl formate, according to the chemical equation: [13] CH 3 OH + CO → HCO 2 CH 3. In industry, this reaction is performed in the liquid phase at elevated pressure. Typical reaction conditions are 80 °C and 40 atm. The most widely used base is ...
In chemistry, metal hydroxides are a family of compounds of the form M n+ (OH) n, where M is a metal. They consist of hydroxide ( OH − ) anions and metallic cations , [ 1 ] and are often strong bases .

A polar aprotic solvent is a solvent that lacks an acidic proton and is polar. Such solvents lack hydroxyl and amine groups. In contrast to protic solvents, these solvents do not serve as proton donors in hydrogen bonding, although they can be proton acceptors.
