NangonaphenoI-l kunye ne-ketone zimveliso ze-co, imiyalelo yokusetyenziswa kwe-phenol kunye ne-acetone yahluke kakhulu. I-acetone isetyenziswa ngokubanzi njengekhemikhali ephakathi kunye ne-solvent. Umlambo osezantsi kakhulu yi-isopropanol, i-MMA kunye ne-bisphenol A.
Kuxelwe ukuba imakethi ye-acetone yehlabathi ikwimeko yokugqithiswa. Imarike yaseTshayina yeyona ndawo ibalulekileyo ekuhanjisweni kwempahla yehlabathi. Okwangoku, iChina isenomthamo ophezulu wokungeniswa kwe-acetone, kwaye unikezelo lwasekhaya luyanda.
Nangona kunjalo, kwicala lemfuno, ngaphandle kophuhliso lwe-bisphenol A, izinga lokukhula lenye imveliso enkulu esezantsi licotha, okukhokelela ekukhuleni okucothayo kwemfuno ye-acetone kunokukhula konikezelo, kunye nokukhula okucothayo kwemfuno kunomgangatho ophakathi kwiminyaka emihlanu yakutshanje, engabangeli ukunyuka kwexabiso.
Kwi-2022, kunye nokuphuhliswa kwe-acetone ezantsi, umlinganiselo wokusetyenziswa kwezantsi utshintshe kakhulu, kwaye i-bisphenol A kunye ne-MMA iyona nto ibaluleke kakhulu kwi-acetone ephantsi. Umthamo we-MMA uya kwanda nge-47% kwi-2022, kwaye umyinge wokukhula kwamandla ngonyaka uya kuba ngama-25% kwi-2018-2022. Ngexesha elithile, imfuno ye-acetone nayo inendima exhasayo.
Umthamo wemveliso ye-isopropanol kwinqanaba lokuqala liye lancipha kakhulu, kwaye ukusetyenziswa kwe-isopropanol kuya kubonisa ukukhula kwe-zero kwi-2022, kunye nomyinge wokukhula wonyaka we-5% kwi-2018-2022. Nangona kunjalo, imakethi yokuthumela ngaphandle kwe-isopropanol ilungile. Ngowama-2022, umthamo wokuthunyelwa kwemveliso kumazwe angaphandle uza kunyuka ngama-62%, uqhube imveliso yangaphakathi ukuba ikhule nge-9%, kwaye iphumeze olona hlumo luphezulu kwikhonkco lemizi-mveliso ngengeniso epheleleyo ye-188%.

Ukukhula kwemfuno ye-acetone kuyacotha, kwaye uxinzelelo lwexabiso kulindeleke ukuba lubekho
Nangona i-phenol kunye ne-ketone ziyimveliso edibeneyo, imiyalelo yokusetyenziswa kwe-phenol kunye ne-acetone yahluke kakhulu. I-acetone isetyenziswa ngokubanzi njengekhemikhali ephakathi kunye ne-solvent. Umlambo osezantsi kakhulu yi-isopropanol, i-MMA kunye ne-bisphenol A.

Kwi-2022, kunye nokuphuhliswa kwe-acetone ezantsi, umlinganiselo wokusetyenziswa kwezantsi utshintshe kakhulu, kwaye i-bisphenol A kunye ne-MMA iyona nto ibaluleke kakhulu kwi-acetone ephantsi.
