I-acetoneNgaba lulwelo olungenabala, oluguqukayo nge-odor eyomeleleyo. Isetyenziswe ngokubanzi kumashishini ahlukeneyo, njengamayeza, ipetroleum, iikhemikhali, njl. Njl.
Ukuveliswa kwe-acetone ikakhulu kubandakanya amanyathelo amabini: inyathelo lokuqala kukuvelisa i-acetic acid ngokuncitshiswa kwesitayile, kwaye inyathelo lesibini kukwahlukana nokucoca i-acetolo.
Kwinyathelo lokuqala, i-acetic acid isetyenziswa njengezixhobo eziluhlaza, kwaye i-catalyst isetyenziselwa ukwenza i-catalytic yokuncitshiswa kwendlela yokufumana i-acetone. I-catalysts esetyenziswayo esetyenziswa yi-zinc powder, i-iron powder, njl njl.→I-Ch3coch3. Ubushushu bokuphendula buyi-150-250℃, kwaye uxinzelelo lokuphendula yi-1-5 MPA. I-winc powder kunye ne-iron powder ihlaziyiwe emva kokuphendula kwaye inokusetyenziswa ngokuphindaphindiweyo.
Kwinqanaba lesibini, umxube oqukethe i-acetone wahlukane kwaye wahlanjululwa. Zininzi iindlela zokwahlula kunye nokucoca i-acetone, ezinjengeendlela zokuhlangana, indlela yokuqonda, indlela yokukhupha, njl. Njl. Le ndlela isebenzisa iindawo ezahlukeneyo zokubila kwezinto zokuwahlulahlulahlulahlula. I-Acetone inendawo ebilayo ephantsi kunye noxinzelelo oluphezulu lwe-vapor. Ke ngoko, inokwahlulwa kwezinye izinto ngenzondelelo phantsi kwendawo ephezulu yeVenuum kwiqondo lokushisa eliphantsi. I-acetone eyahlukileyo emva koko ithunyelwe kwinkqubo elandelayo yonyango.
Isishwankathelo, ukuveliswa kwe-acetone kubandakanya amanyathelo amabini: Ukuncitshiswa kwe-acetic acid ukufumana i-acelitye kunye nokwahlukana nokucocwa kweAcetone. I-Acetone sisixhobo esibalulekileyo sekhemikhali kwi-petroleum, iikhemikhali, amayeza kunye namanye amashishini. Inoluhlu olubanzi lwezicelo kwimizi-mveliso kunye nobomi. Ukongeza kwezi ndlela zilapha ngasentla, zikho ezinye iindlela zokwenza i-Acetone enemveliso, njengendlela yokuxhwila kunye nendlela ye-hydrogeny. Ezi ndlela zineempawu zazo kunye nezibonelelo kwizicelo ezahlukeneyo.
