3 4-Dimethylbenzophenone (CAS# 2571-39-3)

Nhanganyaya

3,4-Dimethylbenzophenone, inozivikanwawo seketocarbonate kana Benzoin. Inotevera rondedzero yehunhu hwayo, kushandiswa, kugadzirira uye ruzivo rwekuchengetedza:

Zvakasikwa:

-Kuonekwa: 3,4-Dimethylbenzophenone ichena crystalline yakasimba.

-Solubility: Inenge isingasviki mumvura, uye ine high solubility mu organic solvents yakadai se ethanol uye dimethylformamide.

-Kunyunguduka: Nzvimbo yakanyunguduka ye3,4-dimethylbenzophenone inenge 132-134 degrees Celsius.

-Chemical properties: Iyo inonzi electrophilic reagent inogona kutora chikamu mune zvakasiyana-siyana zvakadai sehydrogen bond formation, oxidation-reduction reaction pakati peketone carbon uye methyl.

Shandisa:

- 3,4-Dimethyl benzophenone inonyanya kushandiswa se reagent ye organic synthesis reactions.

-Inogona kushandiswa se electrophilic reagent kutora chikamu mumagetsi ekuwedzera maitiro, ketone carbonate formation uye mamwe maitiro.

-Inogona zvakare kushandiswa sephotosensitizer ye lithography, kurapa kwechiedza uye mamwe minda.

Kugadzirira nzira:

Imwe nzira yekugadzirira -3,4-dimethyl benzophenone ndiyo synthesis reaction yebarone. Matanho ekuita ndeaya anotevera: Chekutanga, styrene inobatwa nebromine yakawandisa pasi pechiedza kana ultraviolet mwenje kuumba β-bromostyrene. Iyo β-bromostyrene inobva yaitwa ne hydroxide (eg, NaOH) kuita 3,4-dimethylbenzophenone.

-Imwe nzira yekugadzirira ndeyekuita acetophenone uye sodium bromide pasi pemamiriro e-alkaline kuti ibudise 3,4-dimethyl benzophenone.

Zvekuchengetedza

- 3,4-Dimethylbenzophenone haina chepfu.

-Dzivisa ganda kubata uye inhalation paunenge uchishandisa.

-Ruyi yekunze kusangana neganda, inofanira kubva yasuka nemvura yakawanda.

-Kana wafemerwa, famba nekukasika uende kunzvimbo ine mhepo.

-Inokurudzirwa kupfeka magirovhosi ekudzivirira akakodzera uye midziyo yekufema panguva yekushanda.

-Paunenge uchishandisa nekuchengetedza, ndapota tevera nzira dzakachengeteka dzekushanda uye uiise kunze kwekusvika kwevana.
