Hordhac

Butyl mercaptan waa iskudhis organic ah. Kuwa soo socdaa waa hordhac dabeecadeeda, isticmaalkeeda, hababka wax-soo-saarka iyo macluumaadka badbaadada:

 

Tayada:

- Muuqashada: Butyl mercaptan waa dareere huruud ah oo aan midab lahayn ama iftiin leh oo leh ur ur xun.

- Solubility: Butyl mercaptan wuxuu ku milmi karaa biyo, alkohol iyo ethers, wuxuuna kaga falcelin karaa walxaha acidic iyo alkaline.

- Xasilooni: Butyl mercaptan hawadu way xasiloon tahay, laakiin waxay la falgashaa ogsijiin si ay u samayso sulfur oxides.

 

Isticmaal:

- Kiimikada reagen: Butyl mercaptan waxaa loo isticmaali karaa sidii walax vulcanizing ah oo inta badan loo isticmaalo falcelinta synthesis organic.

 

Habka:

Waxaa jira dhowr siyaabood oo loo diyaariyo butyl mercaptan, oo ay ku jiraan labada hab ee soo socda:

Ku darida ethylene iyo baaruud: Adigoo ka falcelinaya ethylene leh baaruud, butyl mercaptan waxaa lagu diyaarin karaa iyadoo la xakameynayo heerkulka falcelinta iyo waqtiga falcelinta.

- falcelinta sulfation of butanol: butanol waxa lagu heli karaa falcelinta butanol leh hydrogen sulfide ama sodium sulfide.

 

Macluumaadka Badbaadada:

- Aad u kacsan: Butyl mercaptan waxa uu leeyahay isbedel badan iyo ur xamaasad leh, waana in laga fogaadaa neefsashada gaasaska badan.

- Xanaaq: Butyl mercaptan waxa ay saameyn xun ku leedahay maqaarka, indhaha iyo mareenka neef-mareenka, sidaa awgeed waa in biyo lagu luqluqdo waqti ka dib marka la taabto, waana in laga fogaado taabashada ama neefsashada gaasaska badan.

- Sumaynta: Butyl mercaptan waxay saameyn sun ah ku yeelan kartaa jidhka bini'aadamka iyadoo xaddigeedu sarreeyo, waana in fiiro gaar ah loo yeesho badbaadada isticmaalkeeda iyo kaydinta.

 

Marka la isticmaalayo butyl mercaptan, waa in la raaco habraacyada maaraynta badbaadada leh ee kiimikooyinka khuseeya waana in la bixiyaa qalab ilaalin oo habboon sida galoofyada, muraayadaha iyo dharka ilaalinta.
