Hordhac

Tert-butylphenol waa unug dabiici ah. Kuwa soo socdaa waa horudhac ku saabsan sifooyinka, isticmaalka, hababka diyaarinta iyo macluumaadka badbaadada tert-butylphenol:

 

Tayada:

- Muuqashada: Tert-butylphenol waa crystalline adag oo aan midab lahayn ama huruud ah.

- Solubility: Waxay leedahay milmayn hoose oo biyaha ah iyo milmayn wanaagsan oo dareerayaasha organic.

- caraf udgoon: waxay leedahay caraf udgoon gaar ah oo phenol ah.

 

Isticmaal:

- Antioxidant: Tert-butylphenol waxaa inta badan loo isticmaalaa sida antioxidant-ka ee xabagta, rabadhka, balaastikada, iyo walxaha kale si loo kordhiyo cimrigiisa.

 

Habka:

Tert-butylphenol waxaa lagu diyaarin karaa nitrification p-toluene, ka dibna hydrogenated si loo helo tert-butylphenol.

 

Macluumaadka Badbaadada:

- Tert-butylphenol waa guban kara oo waxay keentaa khatar dab iyo qarax marka uu la kulmo holac furan ama heerkul sare.

- Soo-gaadhista tert-butylphenol waxay saameyn xun ku yeelan kartaa maqaarka iyo indhaha waana in laga fogaado.

- Tallaabooyinka ilaalinta shakhsi ahaaneed ee habboon sida galoofyada iyo muraayadaha indhaha ayaa loo baahan yahay marka la qabanayo tert-butylphenol.

- Tert-butylphenol waa in laga fogeeyaa holca iyo oxidants iyo walxaha kale, lagana ilaaliyo meel aanay gaadhin caruurtu. Marka la tuuro, waa in la tuuraa si waafaqsan xeerarka deegaanka.
