Starch, ethylene, phosphoric acid, sulfuric acid, glucoamylase, and its derivative products are ethanol solution of hydrochloric acid, selenium disulfide, ethylene oxide, p-diethylbenzene, biphenyl, 6- methoxy -2- acetylnaphthalene, pentyl cyanoterphenyl, acetaldehyde, formaldehyde, sodium ethoxide, ether, ethyl acetate, ethanol (anhydrous), raspberry ketone, etc.
Among them, the raw material of fermentation method can be agricultural products containing starch, such as cereals, potatoes or fruits of wild plants; Waste molasses from sugar mills can also be used; Or use sawdust containing cellulose, plant stalks, etc. These substances can be pretreated, hydrolyzed and fermented to produce ethanol.
