Hordhac

Cresol, oo kiimiko ahaan loo yaqaan methylphenol (magaca Ingiriisiga Cresol), waa iskudhis organic. Kuwa soo socdaa waa horudhac ku saabsan sifooyinka, isticmaalka, hababka diyaarinta iyo macluumaadka badbaadada p-toluenol:

 

Tayada:

Muuqaalka: Cresol waa dareere aan midab lahayn ama huruud ah oo leh caraf udgoon gaar ah.

Solubility: Waxay ku milmay alkolada, ethers iyo ethers, iyo in yar oo ku milmay biyaha.

Waxyaabaha kiimikada: Cresol waa walax acidic ah oo la falgasha alkali si ay u sameyso milix u dhigma.

 

Isticmaal:

Isticmaalka warshadaynta: Cresol waxa loo isticmaalaa sidii wax-ilaaliye, jeermis-dile, iyo dareere ahaan marka la soo saarayo waxyaabaha ilaaliyayaasha ah. Waxa kale oo ay u shaqeysaa sidii kicin iyo dareere ee warshadaha caagga iyo xabagta.

Isticmaalka beeraha: Toluene waxaa loo isticmaali karaa qaybta beeraha sida cayayaanka iyo fungicides.

 

Habka:

Waxaa jira siyaabo badan oo loo diyaariyo toluenol, mid ka mid ah taas oo caadi ahaan loo isticmaalo in lagu helo iyada oo loo marayo falcelinta oksaydhka ee toluene. Talaabada gaarka ah waa in marka hore la falgaliyo toluene leh ogsijiin si loo soo saaro toluol hoos yimaada ficilka kicinta.

 

Macluumaadka Badbaadada:

Cresol waa sun, taabashada tooska ah ama neefsashada xaddi badan oo crsol waxay waxyeelo u keeni kartaa caafimaadka. Nidaamyada hawlgalka badbaadada ee khuseeya waa in la raaco marka la isticmaalayo, waana in la isticmaalo qalab ilaalin habboon.

Ka fogow taabashada maqaarka oo dheer kana fogow in aad neefsato uumiga.

Marka la kaydinayo oo la maaraynayo toluenol, waxay u baahan tahay in si fiican loo xidho oo loo kaydiyo meel ka fog dabka iyo heerkulka sare.
