Abstract
Inventia se refera la un procedeu de obtinere a butilmalonatilor de dialchil inferior, bromura de butil si carbonat de potasiu conform caruia reactia se realizeaza prin încalzirea reactantilor în raport molar malonat de dialchil pe bromura de butil/carbonat de potasiu de 1/1,2...1,5/ 0,7...1/, mentinînd masa de reactie la temperatura de reflux cu separarea continua a apei timp de 12...15h.The invention relates to a process for the preparation of dialkyl lower butyl halides, butyl bromide and potassium carbonate, according to which the reaction is carried out by heating the reactants in a molar malonic dialkyl analogue on 1: 1 butyl bromide / carbonate. .1.5 / 0.7 ... 1), maintaining the reaction mass at reflux temperature with continuous water separation for 12-15h.
