Abstract
The present invention provides a production method with which high molecular alcohols having an even number of carbon atoms such as 1-butanol, hexanol, octanol and decanol, and a mixture of these are efficiently collected through clean processes with the use of ethanol as a raw material. High molecular alcohols are produced from ethanol by using calcium phosphate-based compounds such as hydroxyapatite Ca10(PO4)6(OH)2, tricalcium phosphate Ca3(PO4)2, calcium monohydrogen phosphate CaHPO4.(0˜2)H2O, calcium diphosphate Ca2P2O7, octacalcium phosphate Ca8H2(PO4)6.5H2O, tetracalcium phosphate Ca4(PO4)2O or amorphous calcium phosphate Ca3(PO4)2. nH2O as a catalyst, using ethanol as a starting material, and setting a contact time at 0.4 second or longer.
