Intangiriro
Dimethyldione nikintu cyimiti gifite izina ryimiti methylbenzophenone. Ibikurikira nintangiriro kumiterere, imikoreshereze, uburyo bwo gutegura namakuru yumutekano ya dimetethone:
Ubwiza:
- Kugaragara: Amazi adafite ibara cyangwa yijimye yumuhondo.
- Gukemura: Gukemura mumazi, alcool hamwe na ether.
- Impumuro: Hamwe n'impumuro nziza idasanzwe.
Koresha:
- Dimethyldiketone ikoreshwa cyane muri synthesis ya chimique nkigisubizo, igabanya agent na catalizator.
- Irashobora gukoreshwa nkintera yingenzi mugihe cyo guhuza ibinyabuzima kandi ikagira uruhare muguhuza ibice bitandukanye byingirakamaro.
Uburyo:
- Uburyo bukoreshwa muburyo bwo gutegura ni ugukora aside ya benzoic hamwe na acide sulfurike cyangwa aside fosifori kugirango ubone chloride ya benzoyl, hanyuma ukoreshe methanol na karubone ya sodium kugirango ubone dimethyldione.
- Hariho ubundi buryo bwinshi bwo gutegura dimethyldione, nka acide chloroformic na reaction ya fenylisocyanate, na chloroazobenzene na reaction ya dimethylamine, nibindi.
Amakuru yumutekano:
- Dimethyldiketone nuruvange kama nuburozi runaka, kandi guhura cyane cyangwa guhumeka birashobora kwangiza umubiri wumuntu.
- Methadiketone igomba kubikwa mu kintu cyumuyaga, kure y’umuriro na okiside.
- Kwambara uturindantoki two kurinda hamwe na gogles mugihe ukoresha kandi wirinde guhura nuruhu cyangwa amaso.
- Uburyo bukoreshwa mubikorwa byumutekano hamwe nubuyobozi bigomba gukurikizwa mubikorwa bya laboratoire cyangwa inganda.
