Nhanganyaya
4,4'-Dimethoxybenzophenone, inozivikanwawo seDMPK kana Benzilideneacetone dimethyl acetal, inhengo yehupenyu. Inotevera sumo yezvivakwa, mashandisirwo, nzira dzekugadzirira uye ruzivo rwekuchengetedza kwekomputa iyi:
Hunhu:
4,4′-Dimethoxybenzophenone imvura isina ruvara kusvika kucheneruka ine hwema hwebenzene. Inobatidza moto, ine density yakakwira, uye inonyungudika muzvinonyungudutsa zvakajairika senge ethanol, ethers, uye ketones. Haina kugadzikana kumhepo uye chiedza uye inogona kupinda oxidation reactions.
Shandisa:
4,4′-dimethoxybenzophenone inowanzoshandiswa sechinhu chinokonzera kana reagent mu organic synthesis uye ine basa rakakwirira. Mune organic synthesis, inogona kushandiswa mukugadzirira aldehydes, ketoni, nezvimwe.
Nzira:
Nzira yekugadzirira ye 4,4′-dimethoxybenzophenone inogona kuwanikwa kuburikidza nekuita condensation ye dimethoxybenzosilane uye benzophenone. Dimethoxybenzosilane inobatwa ne sodium borohydride kuti iwane boranol, yozokoneswa nebenzophenone kuti iwane 4,4′-dimethoxybenzophenone.
Zvekuchengetedza
4,4′-Dimethoxybenzophenone inogumbura ganda uye inogona kukonzera kushatirwa kwemaziso uye nzira yekufema. Matanho akakodzera ekudzivirira akadai semagirovhosi, magirovhosi, uye zvinofema anofanira kupfekwa panguva yekubata nekushandisa. Panguva yekuchengetedza, inofanira kuchengetwa munzvimbo inotonhorera, yakaoma, kure nekupisa uye oxidants. Ndokumbira uteedzere nzira dzakachengeteka dzekushanda uye tevera zvese zvinoenderana nemitemo uye zvinodiwa. Muchiitiko chetsaona, matanho akakodzera ekukurumidzira anofanirwa kutorwa nekukurumidza.
