Bromide Solution Application

Bromide Treatment can be made use of to make photo paper, boards, and pharmaceutical synthesis intermediates.

1) Prepare a Bromide Solution base, which fixes the technical problem that the traditional Fourier variable infrared method can not carry out infrared scanning of singular pieces of ruby minerals less than 1 mm. The potassium bromide base consists of potassium bromide tablets and potassium bromide A hollow sample chamber is provided on the surface of the tablet computer. Area the sample to be found in the hollow instance chamber on the potassium bromide base, after that place it under an infrared microscopic lense. Close the door of the infrared microscopic lense, leave and tons it with argon. Check and assess The concentration circulation of the N element from the within to the outside of the sample to be tested can be obtained. The potassium bromide base makes use of pure potassium bromide tablets as the base of ruby solitary minerals, which deals with the trouble of history disturbance when numerous other substances manage extremely small minerals.

2) Prepare a degradable polybutylene adipate/potassium bromide composite material: 1) Grind the potassium bromide pieces and vacuum completely dry them for later on use; 2) Place PBA in a volumetric flask and make use of an exceptional solvent Change the volume of CHCl3 to entirely liquify PBA; 3) Consist Of KBr to the ready PBA alternative to acquire a KBr mix option; 4) Add ionized water to the gotten PBA services with various elements of KBr, and ultrasonicate the volumetric flask at space temperature degree to prepare Obtain PBA/KBr suspension casting fluid; 5) Utilize the obtained PBA casting liquid through spin finish technique to get a composite motion picture. Wait until the solvent CHCl3 is entirely volatilized at area temperature and hoover completely dry for 6 hours; 6) The prepared The composite motion picture is cultured at a constant temperature to get rid of thermal history; 7) The composite film that gets rid of the thermal background is cultured at a constant temperature to totally recrystallize it; 8) The totally taken shape item symphonious 3) is cooled to space temperature level for detection; the process is fundamental and medical, and the cost is minimized, the procedure is manageable, is anticipated to be industrialized, and has terrific possible application leads and financial advantages.

3) Synthesis of 2-amino-3,5-dibromobenzaldehyde with Bromide Service, consisting of actions: (1) Stir ethanol, water, and o-nitrobenzaldehyde, and warm till all strong o-nitrobenzaldehyde is liquified; (2 ), add reduced iron powder, and include 3 to 5 decreases of hydrochloric acid, mix entirely and stay to heat up until the reaction system reaches the reflux temperature level, and preserve mixing the reaction; (3 ), filter the reaction solution, and stir and drop into the resulting filtrate. Consist of a blend of bromine, potassium bromide and water. After the dropwise improvement is finished, preserve the temperature degree and mix the action; (4) Include excess saturated sodium bicarbonate service to the reaction alternative, mix thoroughly, and filter if solid precipitates. Acquire 2? Amino? 3,5 dibromobenzaldehyde. The reaction of the advancement naturally includes the two-step feedbacks of decline and bromination, neglects the procedure of obtaining the intermediate thing anthranilic aldehyde, simplifies the procedure, and decreases the job.

Bromide Solution Preparation

In industry, bromine and K2CO3 are typically used as basic materials, and commercial KBr is produced by urea decrease approach. The reaction formula is as follows.

The conversion rate of this response is very high. Most of the liquified substances in the response remedy are KBr, which is close to saturation, while the web content of various other materials is really little, much from reaching saturation. If you select a solvent that has a strong impact on KBr precipitation, KBr crystals can be precipitated, while various other materials will certainly remain in the solution, to ensure that KBr can be divided from contaminations. Methanol, ethanol and acetone all have a strong speeding up effect on KBr in liquid remedy [2], and the effect of methanol is obviously far better than that of ethanol and acetone, so methanol should be used as the precipitating agent. Add an ideal quantity of methanol to the response completed option, take shape and precipitate part of KBr, and after cleaning and drying out, the reagent KBr can be obtained. The remaining remedy can be additionally made use of to prepare industrial KBr.

Process actions: Prepare a commercial K2CO3 saturated aqueous solution, warmth it to regarding 55 ° C, include a proper quantity of urea, and add industrial grade bromine while mixing until the reaction solution warms up to regarding 80 ° C and has a pH of 7-8. Bromine

The added quantity is slightly less than the stoichiometric amount, triggering a mild unwanted of K2CO3 in the reaction remedy. Remove the insoluble contaminations in the finished response service while it is warm, cool it to about 30 ° C, and include a suitable quantity of methanol (0.4 L methanol/L finished option) to precipitate KBr, with the precipitation quantity having to do with 35%. Wash the filtered strong with a percentage of pure water and completely dry it to become the reagent KBr. The cleaning liquid is utilized to prepare K2CO3 saturated liquid. Methanol is recovered utilizing a two-step procedure. Initially, methanol and part of the water are gotten rid of by dissipation, to ensure that the remaining solution comes to be a KBr saturated solution. The condensate is evaporated and methanol is obtained by distillation for recycling. Great the staying option to concerning 30 ° C, then add an ideal quantity of methanol (the quantity ratio of methanol to service is about 2:1) to precipitate the KBr in it. The precipitation quantity has to do with 85%. After filtering system and drying, commercial KBr is acquired. The two-step technique is still made use of to recoup methanol, yet when vaporizing, it is only needed to generally evaporate the methanol, and the option is not called for to be filled with KBr.
