Intangiriro

Dimethyl sulfide (izwi kandi nka dimethyl sulfide) ni ifumbire mvaruganda ya sulfuru. Ibikurikira nintangiriro kumiterere, imikoreshereze, uburyo bwo gutegura namakuru yumutekano ya dimethyl sulfide:

 

Ubwiza:

- Kugaragara: Amazi adafite ibara numunuko udasanzwe.

- Gukemura: ntibishobora gukoreshwa na Ethanol, ethers, hamwe na solge nyinshi.

 

Koresha:

- Inganda zikoreshwa mu nganda: Dimethyl sulfide ikoreshwa cyane nkumuti wa synthesis organic reaction, cyane cyane muri sulfidation na thioaddition reaction.

 

Uburyo:

- Dimethyl sulfide irashobora gutegurwa nuburyo butaziguye bwa Ethanol na sulfure. Ubusanzwe reaction iba mubihe bya acide kandi bisaba gushyuha.

- Irashobora kandi gutegurwa wongeyeho sodium sulfide kuri methyl bromide ebyiri (urugero: methyl bromide).

 

Amakuru yumutekano:

- Dimethyl sulfide ifite impumuro mbi kandi igira ingaruka mbi kuruhu n'amaso.

- Irinde guhura nuruhu n'amaso kandi ufate ingamba zikwiye mugihe ukoresha.

- Mugihe cyo gukoresha no kubika, guhura na okiside na acide zikomeye bigomba kwirindwa kugirango wirinde ingaruka mbi.

- Imyanda igomba kujugunywa hakurikijwe amategeko n'amabwiriza y’ibanze kandi ntigomba kujugunywa.

- Komeza guhumeka neza mugihe cyo kubika no gukoresha.
