One method of producing vinegar is the oxidation of the element - ethanal (acetaldehyde).The reaction proceeds as follows: 2SN3SON + O2 = 2SN3SOONDlya the transaction you need a catalyst - a manganese salt.The reaction takes place at elevated temperature (about sixty degrees).
This method is rapidly replacing other, more profitable from an economic point of view - the reaction of methanol with carbon monoxide.The reaction mechanism is as follows: CH 3 OH + CO = SN3SOONDostoinstvo of this method is the high reaction rate and most higher product y
ield, lack of - is the need to use very expensive catalysts (based on rhodium and iridium), which are not accessible to all because of its high price level.
For vinegar, you can also use the method that has been known since ancient times - the so-called "acetic fermentation" fluids containing alcohol, under the influence of a particular enzyme called alcohol oxidase.In fact, the production of a biochemical method, which proceeds in several steps through the formation of intermediate products.In simplified form, it can be represented as follows: C2H5OH + O2 = CH3COOH + N2O
There is also a method for producing vinegar by the distillation of the fine wood.The raw material for this are the waste wood processing, it is desirable to use hardwoods as waste conifers contain a lot of resin.
for immediate consumption, acetic acid, of course, is not suitable!This will lead to severe poisoning.It must first be converted into vinegar, dilute with water.Typically, the concentration of vinegar is from 3% to 9%.
