Low-alcohol beer This is the preferred method because raising the temperature this late in the brewing process can greatly affect the flavor of the brew. If brewers decide to convert their brew to a non-alcoholic brew they must consider the volume of liquid they have lost during the removal of the alcohol. Typically the volume is reduced by roughly 4%, and to compensate water is added. Another tip would be avoiding using sugar from maize; this simply increases the alcohol content without adding to the flavor or body of the beer. Once the alcohol is removed, one proceeds with the normal finishing
Allyl alcohol be obtained by dehydrogenation of propanol. In the laboratory, it has been prepared by the reaction of glycerol with oxalic or formic acids. Allyl alcohols in general can be prepared by allylic oxidation of allyl compounds by selenium dioxide. Allyl alcohol is converted mainly to glycidol, which is a chemical intermediate in the synthesis of glycerol, glycidyl ethers, esters, and amines. Also, a variety of polymerizable esters are prepared from allyl alcohol, e.g. diallyl phthalate. Allyl alcohol is more toxic than related alcohols. Its threshold limit value (TLV) is 2 ppm. It is a lachrymator. It is classified as an
