1 By the reaction of mannitol and hydrobromic acid.

2 Dibromo neopentyl glycol was prepared from pentaerythritol and hydrobromic acid.

3 Incineration of pyrolysis with recovery of bromine or hydrobromic acid.

4 Bromination of 4-nitroaniline with hydrobromic Acid and hydrogen peroxide as brominating agent in dilute sulfuric acid was studied.

5 Various methods are disclosed to remove the hydrobromic acid vapor from the higher molecular weight hydrocarbons and to generate bromine from the hydrobromic acid for use in the process.

6 Pharmaceutical and Photographic Grade Potassium Bromide, Ammonium Bromide, Hydrobromic Acid, Lithium Bromide as well as organic bromine flame retardants including Tetrabromobisphenol A and so on.

7 N-butanol was prepared with bromine and hydrobromic acid in the laboratory. 1-bromo-butane Preparation reflux device, product purification, etc. optimal design was discussed.

8 Bromododecane was synthesized from n- dodecyl alcohol using byproduct hydrobromic acid from 1-bromoadamantan process as raw material in the presence of the concentrated sulfuric acid.

9 In the experiments, methyl bromide was generated by the reaction of the mixture of hydrobromic acid and methanol on HZSM-5 catalyst.

10 The traditional method for 2,6-dibromoaniline synthesis is hydrolysis of 3,5-dibromo-4-aminobenzene sulfonamide produced from 4-aminobenzene sulfonamide and hydrobromic acid.

11 A salt of a pullulan aminoalkyl ether according to claim 1, wherein the salt -forming acid is hydrochloric acid , hydrobromic acid , sulfuric acid , nitric acid , acetic acid , or oxalic acid .

12 It has the largest production of bromine series chemical in China. Its Hydrobromic Acid production line boasts the most advanced techmology in China.

13 The synthetic method of taurine was improved by shortening the reaction time and decreasing the amount of hydrobromic acid.

14 In organic bromide turn thing production line, it is usually by - product large quantity hydrobromic acid.

15 And in the lappaconitine hydrobromide preparation, the outgrowth and long reaction time were overcome by dibromine alkyl instead of hydrobromic acid.

16 N-octyl bromide was synthesized by hydrobromic method in which took n-octanol and industrial waste hydrobromic acid(48%) as materials, concentrated sulfuric acid as a catalyst.

17 This paper introduces the physicochemical property, use, market condition, synthesis method, technology economic index, invest appraisal and economy effect of hydrobromic acid pyridine salt.
