Hordhac

Pentane. Astaanteedu waa sida soo socota:

Waxay la mid tahay dareerayaal badan oo dabiici ah laakiin maaha biyo.

 

Waxyaabaha Kiimikada ah: N-pentane waa hydrocarbon aliphatic ah oo guban leh oo leh barta iftiimaya hoose iyo heerkulka iswada. Waxa lagu gubi karaa hawada si loo soo saaro kaarboon laba ogsaydh iyo biyo. Qaab dhismeedkeedu waa mid fudud, n-pentane-na waxa ay la falgashaa isku-ydhsiisyada dabiiciga ah ee caadiga ah.

 

Isticmaalka: N-pentane waxaa si weyn loogu isticmaalaa tijaabooyinka kiimikaad, diyaarinta dareeraha iyo isku darka dareeraha, sidoo kale waa alaab muhiim ah oo ceeriin ah oo ku jirta warshadaha batroolka.

 

Habka diyaarinta: n-pentane waxaa inta badan lagu helaa dildilaac iyo dib u habeyn lagu sameeyo habka sifaynta batroolka. Alaabta batroolka ee ay soo saaraan hababkani waxay ka kooban yihiin n-pentane, taas oo la kala saari karo oo lagu nadiifin karo si loo helo n-pentane saafi ah.

 

Macluumaadka badbaadada: n-pentane waa dareere guban kara waana in laga fogeeyaa ololka furan iyo kulaylka sareeyo. Waa in lagu isticmaalo meel hawo fiican leh oo iska ilaali inaad la xiriirto walxaha oksaydhka ee xooggan. Soo-gaadhista muddada-dheer ee n-pentane waxay keeni kartaa maqaar qallalan oo xanaaqsan, waana in la qaado tillaabooyinka ilaalinta habboon sida galoofyada iyo muraayadaha indhaha. Haddii ay dhacdo neefsashada shil ah ama taab maqaarka n-pentane, u raadso gargaar caafimaad isla markiiba.
