Ibipimo by'ubucucike bw'umurongoGutanga ubwenge bw'ingenzi mu gutunganya acetophenone mu gukoresha parufe. Gupima ubucucike mu gihe nyacyo bituma hubahirizwa amabwiriza agenga ubuziranenge bwa acetophenone, bigafasha mu kubona buri gihe imyanda ya benzene na acetyl chloride iri munsi ya 0.5%. Abakora banonosora uburyo bwo gutunganya neza no guhindura uburyo bwo kugabanya ubucucike mu buryo bwikora kugira ngo bagumane acetophenone iri hagati ya 99.5%. Mu gihe cyo kuvanga no guhuza mu gukora parufe, metero zipima ubucucike bw'imirongo zishimangira ubucucike bw'imirongo y'ibinyabuzima kugeza kuri 1.045–1.050 g/cm³, bikarinda ko oxime hydrolysate ibaho binyuze mu kubona hakiri kare.
AsetofenoneIncamake y'uburyo umusaruro ukorwa
Oxidation ya ethylbenzene ikora acetophenone, ikoreshwa na acetasi za cobalt cyangwa manganese kuri 120-200°C kugira ngo itange umusaruro ugera kuri 90%. Gutandukanya ibice byinshi bikuraho phenylethane na hydroperoxides, hanyuma ikoreshwa rya precision fractional distillation ritandukanya acetophenone. Ibipimo by'ubucucike bw'imirongo bigenzura ubuziranenge bwa distillate, bigatuma habaho guhindura reflux ratio mu gihe nyacyo kugira ngo bikomeze acetophenone ≥99.5%, ingenzi mu gukoresha parufe. Uburyo bwo gupima ubucucike bworohereza kubona imyanda ya benzene na acetyl chloride—kubungabunga urwego rwa 0.5% ni ingenzi mu gutunganya acetophenone. Igenzura ryikora ku murongo rituma reflux ya distillation iba hagati ya 2:1 na 3:1, kunoza gukuraho imyanda no kugabanya amakosa yo mu maboko.
Mu gihe cyo gusohora dichloromethane, gukuramo dichloromethane bigabanya ubucucike bw'ibinyabuzima buri hagati ya 1.045–1.050 g/cm³, bigakurikiranwa mu buryo butaziguye hakoreshejwe ibikoresho bya Lonnmeter inline density. Ubu bucucike bubuza ikorwa rya oxime hydrolyzate kandi bukagenzura iyongera rya sodium hydroxide. Kugabanuka k'ubucucike bigaragaza ko gukuramo bidakozwe neza, bigatera uburyo bwo gukora neza acetophenone isuku cyane. Gupima mu buryo burambuye bituma habaho guhuza no guhuza neza, bigashyigikira amahame y'ubuziranenge bwa acetophenone no gukora impumuro nziza.

Imbogamizi mu gupima ubucucike bw'umubiri
Gupima ubucucike bw'imitsi mu gutunganya acetophenone bihura n'imbogamizi zikomeye mu bya tekiniki no mu mikorere:
Gupima imyanda ya benzene na acetyl chloride iri munsi ya 0.5% birakenewe kugira ngo huzuzwe amahame ngenderwaho ya acetophenone mu gukoresha parufe. Itandukaniro ry'ubucucike riri hasi ya 0.0005 g/cm³ rigomba gukurikiranwa kugira ngo habeho uburyo bwo gukuraho imyanda vuba no kuyikosora ako kanya.
Uburyo bwo gusya neza bukoresha uburyo bwo gusubiza mu buryo bwihuse ubucucike kugira ngo bugumane igipimo cyo gusubiramo ubucucike (2: 1–3: 1). Kugenzura ubucucike cyane birinda ko ibicuruzwa bitakaza agaciro kabyo no gutakaza ibikoresho fatizo. Ihindagurika ryerekana itandukaniro mu buziranenge bwa acetophenone cyangwa kuvanga no guhuza impumuro mu buryo butuzuye.
Uburyo bwo gukora oximation busaba kumenya neza aho ibintu bigarukira. Ibikoresho biri ku murongo bigomba kumenya igipimo cy'ubwiyongere bw'ubucucike bwa ≤0.001 g/cm³/h kugira ngo hagenzurwe neza kandi hifashishijwe uburyo bwa alkali, hirindwa ko sodium hydroxide irenze urugero mu gukora organic synthesis.
Gukuramo dichloromethane mu buryo butuzuye bigaragara nk'igabanuka ry'ubucucike mu cyiciro cy'ibinyabuzima. Ibipimo by'ubucucike bya Lonnmeter bifasha mu kunoza umuvuduko w'amazi aturuka ku bimera, bigatuma ubucucike bw'ibimera buhagarara neza kuri 1.045–1.050 g/cm³ mu gihe cyo kugenzura imikorere ya acetophenone oxime.
Gukumira neza oxime hydrolysate biterwa no kumenya igihe nyacyo ingaruka ziterwa n'imiti. Ibimenyetso byo gupima ku murongo igihe cyo guhagarika kurya alkali mbere yuko ibicuruzwa bitangira.
Ibyiza byo Guhuza Ibipimo by'Ubucucike bw'Umurongo
Igenzura ry’ibicuruzwa byikora rijyanye n’ubucucike bw’ibicuruzwa rituma amazi asohoka gusa hejuru ya 1.027 g/cm³, bigabanya cyane kurekurwa kw’ibintu bito. Gukurikirana ubucucike buhoraho bituma habaho guhita haboneka imyanda ya benzene na acetyl chloride iri munsi ya 0.5%, bigatera gukosorwa ako kanya. Ibisubizo byihuse binoza ikigereranyo cyo gusubiramo ibikomoka ku bimera hagati ya 2:1 na 3:1, byongera umusaruro wa acetophenone uri hejuru ya 99.5% mu gihe bigabanya imyanda y’ibikoresho fatizo. Isesengura ry’umurongo rikuraho ifatwa ry’ibipimo n’intoki, rigabanya igihe cyo gutegereza ingero n’amakosa y’abantu, kandi rigabanya igihe mpuzandengo cyo kugenzura ubuziranenge ku kigero kirenga 40%. Amakuru ahoraho y’umurongo atuma habaho guhagarara no guhuza, agakomeza ubuziranenge bwa acetophenone mu gukoresha parufe mu gihe kirekire. Agaciro kose k’ubucucike n’ivugurura birandikwa, bitanga inyandiko zishobora gupimwa kugira ngo hubahirizwe amahame y’ubuziranenge bwa acetophenone. Ibikoresho bya Lonnmeter bishyigikira ishyirwa mu murongo usanzwe w’ibikorwa, bitanga igenzura nyaryo mu gihe cyo gusohora, gukuramo, no gusohora ibimera mu buryo budahagije.
Gukemura ibibazo bigoye mu mikorere
Saba ibiciro bya Lonnmeter inline density meter kugira ngo urebe uburyo bwo gusukura acetophenone no gushyiraho parufe. Koresha ibikoresho bya Lonnmeter kugira ngo ubone ibyiza byo gupima ubucucike bw'inline, gukoresha neza ikigereranyo cya distillation reflux, no gukoresha neza dichloromethane. Shyigikira inyandiko z'amahame y'ubuziranenge bwa acetophenone, gukosora imikorere yihuse, no gukoresha neza ingano y'amazi asohoka hakoreshejwe sensor zikomeye kandi zitaziguye.
