Zusammenfassung:A method is described for producing n-propyl bromide of a high degree of purity, which contains isopropyl bromide in an amount lower than 0.1% w/w, and usually lower than 0.05%. The method is characterized in that n-propanol is reacted with HBr which is in gas form, preferably dry, and which is in excess over the stoichiometric amount, wherein the excess HBr is at the end of the reaction in an aqueous solution formed from the reaction water. The invention further relates to N-propyl bromide of high purity, containing typically less than 500 ppm of isopropyl bromide.
