2. Kunyungudika: Nzvimbo yakanyunguduka yekomboni iri pakati pe128-130°C.

3. Solubility: Inonyungudika mune mamwe organic solvents, senge ethanol uye dichloromethane, asi isinganyungudika mumvura.

Shandisa:

Acid, 4-bromo-1,5-dimethyl-ine imwe kukosha kwekushandisa mune organic synthesis, uye inonyanya kushandiswa kugadzira skeleton yema organic mamorekuru uye inotungamira maitiro. Inogona kushandiswa sechinhu chepakati chekugadzira mishonga yezvipembenene, mishonga uye dhayi.

Kugadzirira nzira:

Asidhi, 4-bromo-1,5-dimethyl-inogona kugadzirwa nematanho anotevera-:

1. Kutanga, methyl methacrylate uye aniline inobatwa pasi pe catalysis ye alkali kugadzirira 1,5-dimethyl-1H-pyrazole.

2. 1,5-dimethyl -1H-pyrazole inobatwa nehydrogen bromide muhupo hweacetic acid kuti ibudise 4-bromo-1, 5-dimethyl -1H-pyrazole.

3. Pakupedzisira, 4-bromo-1, 5-dimethyl-1H-pyrazole inoshandiswa ne sodium hydroxide kana sodium carbonate kuti ibudise asidi, 4-bromo-1,5-dimethy-.

Zvekuchengetedza

Nezve kuchengetedzeka kweasidhi, 4-bromo-1,5-dimethyl-, zvinotevera zvinhu zvinoda kucherechedzwa:

1. musanganiswa unogona kunge uchitsamwisa maziso, ganda uye hurongwa hwekufema, tapota dzivisa kusangana kwakananga.

2. Panguva yekushandiswa, rega kufema guruva kana mhute yemushonga.

3. Panguva yekushanda uye kuchengetedza, kufefetera kwakanaka uye matanho ekudzivirira emunhu anofanira kutorwa, sekupfeka magirazi ekudzivirira, magirovhosi uye zvipfeko zvakakodzera zvekudzivirira.

4. Kana ukasangana nekomboni iyi, kurumidza kuchenesa nzvimbo yakakanganiswa nemvura yakawanda uye bvunza mazano achiremba wako.

Mashoko aya ndeekutarisa chete. Ndokumbira uverenge uye uteedzere pepa rekuchengetedza data rekemikari yakakodzera usati washandisa.
