Methanol is made by a method different from that used in the preparation of ethanol. The naphtha fraction from the distillation of crude petroleum, is used as a raw material for the manufacture of methanol. When naphtha is reacted with a high steam ratio, under pressure and at a high temperature, synthesis gas of low methane content is obtained.
Most of the carbon from the naphtha is converted to carbon monoxide and carbon dioxide which can be removed from the gaseous mixture to leave a high purity of hydrogen. When a mixture of hydrogen and carbon monoxide in the ratio 2:1 is passed over a catalyst (e.g. a mixture of zinc oxide and chromium oxide) under high pressure and at a high temperature, methanol is formed.
What else can I help you with?
What is the pH of methanol?
The pH of methanol is around 7, considered neutral. This is because methanol is a neutral molecule that does not produce or accept protons in water to significantly alter the pH.
Can you turn methanol into ethanol?
Yes, methanol can be converted into ethanol through a process called catalytic hydrogenation, where hydrogen gas is reacted with methanol over a catalyst to yield ethanol. This process involves changing the molecular structure of methanol to produce ethanol.
What of each reactant would be needed to produce 100.0 kg of methanol?
To produce 100.0 kg of methanol, you would need 50.0 kg of carbon monoxide and 150.0 kg of hydrogen. This is because the reaction to produce methanol from carbon monoxide and hydrogen has a 1:3 ratio.
What can be hydrolysed to form methanol as one of its products?
One example of a compound that can be hydrolyzed to form methanol is methyl acetate. When methyl acetate is hydrolyzed, it reacts with water to produce acetic acid and methanol as the products.
What is the smell when salisielsuur and methanol?
The combination of salicylic acid and methanol does not have a distinctive smell. Salicylic acid itself has a slightly phenolic odor, while methanol has a characteristic alcohol-like scent. When combined, these compounds may not produce a notable smell.
What are the uses of methanol?
Methanol is used- -in paint industry -In perfumery -In aviation Fuel (blending) -to produce formeldehyde -polymers

What happens if sodium methoxide 25 percent in methanol reacts with water?
The sodium methoxide reacts with the water to produce sodium hydroxide an methanol.

Would the alkoxide form if an hydroxide was dissolved in methanol?
No. Alkoxide ions are stronger bases than hydroxide ions. The only way of making an alkoxide is by reacting a hihgly reactive metal such as sodium with the corresponding alcohol (react sodium with methanol to produce sodium methoxide). In water sodium methoxide will react to produce sodium hydroxide and methanol.

Conversion of ethanol into methanol?
The conversion of ethanol into methanol typically involves dehydration, where ethanol undergoes a reaction to form ethylene, which is then further processed to produce methanol through various catalytic processes. However, this conversion process can be complex and may require specific conditions and catalysts to achieve high yields of methanol.
