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.
