Okwu mmalite

Acid, 4-bromo-1, 5-dimethanol-bụ ngwakọta nke usoro kemịkal ya bụ C7H8BrNO2.

Ọdịdị:

1. Ọdịdị: acid, 4-bromo-1,5-dimethyl-white siri ike.

2. Ebe mgbaze: Ebe mgbaze nke ogige ahụ dị n'etiti 128-130 ° C.

3. Solubility: Ọ bụ soluble na ụfọdụ ihe mgbaze organic, dị ka ethanol na dichloromethane, ma ọ dịghị soluble na mmiri.

Jiri:

Acid, 4-bromo-1,5-dimethyl-nwere ụfọdụ ngwa uru na organic njikọ, na tumadi na-eji na-ewu ọkpụkpụ nke organic molekul na ndu mmeghachi omume. Enwere ike iji ya dị ka ihe etiti maka njikọ nke pesticides, pharmaceuticals na dyes.

Ụzọ nkwadebe:

acid, 4-bromo-1,5-dimethyl-nwere ike iji usoro ndị a-:

1. Nke mbụ, methyl methacrylate na aniline na-emeghachi omume n'okpuru catalysis nke alkali iji kwadebe 1,5-dimethyl-1H-pyrazole.

2. 1,5-dimethyl -1H-pyrazole na-emeghachi omume na hydrogen bromide na ọnụnọ acetic acid iji mepụta 4-bromo-1, 5-dimethyl -1H-pyrazole.

3. N'ikpeazụ, 4-bromo-1, 5-dimethyl-1H-pyrazole na-emeghachi omume na sodium hydroxide ma ọ bụ sodium carbonate iji mepụta acid, 4-bromo-1,5-dimethy-.

Ozi nchekwa:

Banyere nchekwa nke acid, 4-bromo-1,5-dimethyl, ihe ndị na-esonụ kwesịrị ka a mara:

1. ogige ahụ nwere ike ịkpasu anya, akpụkpọ ahụ na usoro iku ume, biko zere kọntaktị kpọmkwem.

2. Mgbe a na-eji ya eme ihe, zere ikuru uzuzu ma ọ bụ vapo nke ngwọta.

3. N'oge a na-arụ ọrụ na nchekwa, ekwesịrị ịme ezigbo ikuku ikuku na nchedo onwe onye, ​​​​dị ka iyi mkpuchi mkpuchi, uwe aka na uwe nchebe kwesịrị ekwesị.

4. Ọ bụrụ na ị bata na ngwakọta a, kpochaa ebe ahụ emetụtara na mmiri buru ibu ma kpọtụrụ ndụmọdụ dọkịta gị.

Ozi a bụ naanị maka ntụnye aka. Biko gụọ ma soro mpempe data nchekwa nke kemịkalụ dị mkpa tupu eji ya.
