Phenolwaa walxo kiimiko ah oo aad muhiim u ah, taas oo si weyn loogu isticmaalo soo saarista alaabada kiimikaad ee kala duwan, sida balaastikada, antioxidants, wakiilada daawaynta, iwm. Sidaa darteed, aad bay muhiim u tahay in la barto farsamada wax soo saarka ee phenol.Maqaalkan, waxaan ku soo bandhigi doonaa tignoolajiyada wax soo saarka ee phenol si faahfaahsan.

Diyaarinta phenol guud ahaan waxaa lagu fuliyaa iyadoo la falcelinayo benzene leh propylene iyadoo ay joogaan kiciyayaal.Habka falcelinta waxaa loo qaybin karaa saddex tallaabo: tallaabada ugu horreysa waa falcelinta benzene iyo propylene si ay u sameeyaan cumene;Tallaabada labaad waa oksaydhka cumene si loo sameeyo cumene hydroperoxide;Talaabada saddexaadna waa kala-goynta cumene hydroperoxide si ay u samayso phenol iyo acetone.

Talaabada kowaad, benzene iyo propylene ayaa laga falceliyaa iyadoo ay jirto kiciye asiidh ah si loo sameeyo cumene.Dareen-celintan waxaa lagu sameeyaa heerkul ku saabsan 80 ilaa 100 darajo Celsius iyo cadaadis qiyaastii 10 ilaa 30 kg/cm2.Kataliyaha la isticmaalo badanaa waa aluminium chloride ama sulfuric acid.Badeecada falcelinta waa cumene, kaas oo ka soocay isku dhafka falcelinta by distillation.

Talaabada labaad, cumene waxa lagu ogaysiinayaa hawo iyadoo ay jirto kiciye asiidh ah si uu u sameeyo cumene hydroperoxide.Dareen-celintan waxaa lagu sameeyaa heerkul ku saabsan 70 ilaa 90 darajo Celsius iyo cadaadis qiyaastii 1 ilaa 2 kg/cm2.Daroogada la isticmaalo badanaa waa sulfuric acid ama phosphoric acid.Badeecada falcelinta waa cumene hydroperoxide, taas oo ka soocday isku dhafka falcelinta by distillation.

Talaabada saddexaad, cumene hydroperoxide ayaa lagu kala jeexjeexay joogitaanka kicinta aashitada si loo sameeyo phenol iyo acetone.Dareen-celintan waxaa lagu sameeyaa heerkul qiyaastii 100 ilaa 130 darajo Celsius iyo cadaadis qiyaastii 1 ilaa 2 kg/cm2.Daroogada la isticmaalo badanaa waa sulfuric acid ama phosphoric acid.Badeecada falcelinta waa isku dhafka phenol iyo acetone, kaas oo ka soocay isku-darka falcelinta iyadoo la nadiifinayo.

Ugu dambeyntii, kala-soocidda iyo nadiifinta phenol iyo acetone waxaa lagu fuliyaa nadiifinta.Si loo helo badeecooyin nadiif ah oo sarreeya, tiirar isdaba-joog ah ayaa badanaa loo isticmaalaa kala-soocidda iyo nadiifinta.Shayga ugu dambeeya waa phenol, kaas oo loo isticmaali karo soo saarista alaabada kiimikaad ee kala duwan.

Marka la soo koobo, diyaarinta phenol ee benzene iyo propylene iyada oo loo marayo saddexda tallaabo ee kor ku xusan waxay heli kartaa phenol nadiif ah oo sarreeya.Si kastaba ha ahaatee, habkani wuxuu u baahan yahay in la isticmaalo tiro badan oo ah kiciyayaal aashito ah, taas oo keeni doonta daxal halis ah qalabka iyo wasakhowga deegaanka.Sidaa darteed, qaar ka mid ah hababka diyaarinta cusub ayaa la sameeyay si loo beddelo habkan.Tusaale ahaan, habka diyaarinta ee phenol iyadoo la adeegsanayo biocatalysts ayaa si tartiib tartiib ah loogu dabaqay warshadaha.
