Abstract
Inventia se refera la un procedeu de preparare a 1-brom-hexanonei-5 prin descompunerea 2-metil-3-carbetoxi-5,6-dihidropiranului cu acid bromhidric la care în scopul maririi randamentului reactiei acidul bromhidric este preparat în situ din bromura desodiu si acid sulfuric concentrat.The invention relates to a process for the preparation of 1-bromohexanone-5 by decomposing 2-methyl-3-carbethoxy-5,6-dihydropyran with hydrobromic acid in which, in order to increase the reaction yield, hydrobromic acid is prepared in situ from desodium bromide and concentrated sulfuric acid.
