FIELD: methods of production of 1-butanol (versions), 1,3-butadiene and high-octane fuel from ethanol. SUBSTANCE: all methods include contacting of ethanol with low-crystalline calcium phosphate having specific area at least 2 sq. m/g. Method of synthesis of 1-butanol is realized, as a rule, at Ca/P molar ratio of 1.6- .8 and temperature from 350 to 450 C. In a version of synthesis of 1-butanol, low-crystalline calcium phosphate contains at least one type of metal and/or oxide of metal selected from Bs, Na, K, Li, Cs, Sr, Y, Ce, Sb, Eu, Ti, W and Zr in amount not exceeding 50 molar % to Ca and having (Ca + metal)/P molar ratio from 1 to 2, at temperature from 300 to 450 C. Method of synthesis of 1,3-butadiene is usually conducted at Ca/P molar ratio of 1.55 o 1.8 and temperature from 450 to 700 C. Method of synthesis of high-octane fuel is realized at Ca/P molar ratio of 1.55 to 1.8 and temperature from 300 to 700 C. EFFECT: higher efficiency. 4 cl, 3 dwg, 8 tbl
