Amamitha okuqina angaphakathi ayadingeka ukuze kuqashwe ukusabela kwamakhemikhali ngesikhathi sangempela ekuhlanganisweni kwe-linalyl acetate. Ukufundwa kokuqina okunembile (okuhlosiwe: 0.890–0.894 g/cm³) kuvumela ukulawulwa kokusabela kwe-esterification okuzenzakalelayo ngamamitha okuqina. Idatha eqhubekayo iqinisekisa ukuqapha izinga lokuphakelwa kwe-acetyl chloride, ivimbele ukumunca ngokweqile, okuholela ku-hydrogen chloride eningi kanye nephunga elibi emikhiqizweni yamakha.
Ukulinganisa okuqondile okuqondile kususa ukulibaziseka phakathi kokuhlaziywa kokukhiqiza kanye nokwelebhu, kusekela ukulungiswa kwenqubo okusheshayo kanye nokutholwa kwe-anomaly. Ukuhlanganiswa kwesignali engu-4-20mA kanye nokuxhumana kwe-RS485 kuvumela ukudluliswa kwedatha ngesikhathi sangempela okuzinzile, okumelana nokuphazamiseka ngisho nasezindaweni ezimanzi nezincibilikisayo ze-organic. Ukulawula okuqondile kukhulisa ukuguqulwa kwezinto zokusetshenziswa ngamaphesenti angaphezu kuka-30, kunciphisa imfucuza ye-acetyl chloride kanye ne-linalool.
Ukuqapha ubuningi obuthembekile kulola ukuhambisana komkhiqizo nezindinganiso zobumsulwa ze-GB 29985-2013.Amamitha okuqina amelana nokugqwalangemizimba ye-Hastelloy kanye ne-PTFE lining zigcina ukunemba ngaphansi kokuchayeka kwe-acetyl chloride, ziqinisekisa ubuqotho bemishini. Lezi zinsimbi zibalulekile ekuqapheni okuqhubekayo kwenqubo, ukuvimbela ukuguquguquka kweqembu, kanye nokugcina ikhwalithi yezithako zamakha ngezinga.

Ukulinganiswa Kobuningi Be-Inline ku Li-inalylAi-cetateSukwenziwa
Ukulinganiswa kobuningi be-inline kubalulekile ekuqapheni ukusabela kwamakhemikhali ekuhlanganisweni kwe-linalyl acetate, lapho ukuhlukahluka kobuningi kuthinta ngqo ukulawulwa kokusabela kwe-esterification. Ukuqapha okuqhubekayo kwesikhathi sangempela kuqinisa izilinganiso zokudla ze-linalool ne-acetyl chloride, kuthuthukisa ukuguqulwa kwezinto zokusetshenziswa kanye nokunciphisa imfucuza ye-solvent. Ukuvimbela okuzenzakalelayo komthamo oweqile we-acetyl chloride kusetshenziswa amamitha wobuningi be-inline kunciphisa ukwakheka kwe-HCl okweqile, kuqinisekisa ukulawulwa kwephunga le-hydrogen le-chloride elizinzile emikhiqizweni yamakha.
Amamitha okuqina kwefoloko lokulungisangemizimba ye-Hastelloy kanye ne-PTFE lining imelana nezinyibilikisi eziphilayo ezingenamanzi futhi imelana nokugqwala kwe-acetyl chloride, igcina ukuthembeka kwesignali yokulawula inqubo. Ukuxhumana okuhlanganisiwe kwe-RS485 kanye nokukhishwa kwesignali okungu-4-20mA kusekela ukudluliswa kwedatha okungenamthungo kuma-PLC okukhiqiza, okuvumela ukutholwa okusheshayo kwe-anomaly kanye nokwenza ngokuzenzakalela kokusabela. Lokhu kunemba ekulawulweni kwenqubo kuqinisekisa ukuhambisana namazinga ekhwalithi ye-linalyl acetate (GB 29985-2013) futhi kwandisa ukusebenza kahle kokukhiqiza ngamaphesenti afinyelela ku-30.
Ukubuka konke kweEukuhlanza kweLinalool
Ukwenziwa kwe-linalool esterization okuqhubekayo nge-acetyl chloride ezinyibilikisini eziphilayo ezingenamanzi kukhiqiza i-linalyl acetate, ingxenye eyinhloko yamakha. Le nqubo idinga ukuqapha okunembile kwesilinganiso sokudla kwe-acetyl chloride ukulawula i-stoichiometry ye-reactant kanye nokunciphisa iphunga le-chloride hydrogen emikhiqizweni yamakha. Amamitha obuningi obuphakathi—alungiselelwe i-0.890–0.894 g/cm³ ekugcineni kokuhluzwa—ahlinzeka ngokuqapha ukusabela kwamakhemikhali ngesikhathi sangempela, okusekela ukulawulwa kwenqubo okuzenzakalelayo kanye namazinga ekhwalithi ye-linalyl acetate (GB 29985-2013).
Umkhiqizo ovela ku-reactor ungena esigabeni sokuncibilikisa, lapho amamitha okuqina amelana nokugqwala e-Lonnmeter ane-Hastelloy kanye ne-PTFE lining eqinisekisa ubuqotho bokulinganisa ezindaweni ezinolaka ze-acetyl chloride. Lapho ubuningi bubonisa i-linalyl acetate emsulwa, izinhlelo zamavalvu ezenzakalelayo ziqondisa umkhiqizo ekuqoqweni, ziwuhlukanise nezingxube ezingaphenduliwe ezinobunzima obuphansi. Lezi zingxube ziphinde zisetshenziswe ngokuzenzakalelayo ngokulawula amavalvu ukuze kuthuthukiswe ukuguqulwa kwezinto zokusetshenziswa nokunciphisa imfucuza, kuthuthukiswe ukusebenza kahle kokukhiqiza ngaphezu kuka-30%.
Ukuxhumana okuhlanganisiwe kwe-RS485 kanye nemiphumela yesignali engu-4-20mA kunikeza ukuqapha okuqhubekayo kwenqubo kanye nokutholwa kwe-anomaly, kusekela izenzo zokulungisa ngokushesha kanye nokunciphisa ukuphambuka kwekhwalithi yomkhiqizo. Ukuhlanganiswa okungenamthungo kwamamitha obuningi obungaphakathi kwe-inline kuthuthukisa ukusetshenziswa kwe-solvent futhi kugcina izimo ezingenamanzi ezibalulekile ekulawuleni ukusabela kwe-esterification.

Izinselele Ekulinganisweni Kobuningi Be-Inline
Ukukhukhuleka kobuningi kuhlupha i-esterification yezigaba eziningi, okubangela ukuthi ubumsulwa be-linalyl acetate buye ngaphansi kwe-GB 29985-2013 standard. Ukuxubana kwendawo, ukushintsha kwezinga lokushisa, kanye nokushintshashintsha kokudla kwe-reagent kushintshashintsha ukufundwa kobuningi, okuphazamisa ukulawulwa kokusabela kwe-esterification ngamamitha obuningi. I-Acetyl chloride ihlasela ngokushesha izindawo ezimanzi zenzwa, ikakhulukazi insimbi engagqwali, okuholela ekuhlulekeni kwangaphambi kwesikhathi. Imizimba ye-Hastelloy kuphela ene-PTFE lining eqinisekisa amamitha obuningi amelana nokugqwala ukuze kucutshungulwe amakhemikhali ngaphansi kokuchayeka okuqhubekayo kwe-acetyl chloride.
Ukuthatha amasampula e-batch yendabuko akukwazi ukuletha ukuqapha ukusabela kwamakhemikhali ngesikhathi sangempela ekuhlanganisweni kwe-linalyl acetate. Ukutholwa kwe-anomaly okubambezelekile kuholela ekusetshenzisweni ngokweqile kwe-acetyl chloride kanye namazinga aphezulu e-hydrogen chloride, okubangela ukuphambuka kwephunga. Ukuhlukaniswa kwesigaba okunganele ngesikhathi sokuhlanza kubangela ukuthi i-feedstock engaphenduliwe ingcolise umkhiqizo, okuvimbela ukuqapha izinga lokuphakelwa kwe-acetyl chloride kanye nokunciphisa ukuguqulwa kwezinto zokusetshenziswa.
Izinhlelo zokuxazulula eziqinile ziphazamisa ukuxhumana kwe-RS485 kumamitha obuningi bezimboni futhi zibeka engcupheni ukuhlanganiswa kwesignali okuzinzile okungu-4-20mA kokulawulwa kwenqubo. Ukungazinzi kwesignali okuqhubekayo kuvimbela ukuqapha okuqhubekayo kwenqubo kanye nokutholwa kwe-anomaly, kunciphisa izinzuzo zokusebenza kahle kokukhiqiza futhi kuvimbele ukuhambisana nezindinganiso zekhwalithi ye-linalyl acetate.
Izinzuzo Zokuhlanganisa Amamitha Obuningi Obungaphakathi
Ukulawulwa kobuningi besikhathi sangempela kushintsha ukusebenza kwe-valve ezigabeni zokuhlukanisa, kukhulisa isivuno se-linalyl acetate ngaphezu kuka-30% uma kuqhathaniswa nezindlela ezisekelwe ku-batch. Amamitha angaphakathi abonisa ngokushesha i-acetyl chloride ngokweqile, avimbele ukwakheka kwe-HCl ngokweqile futhi alondoloze ukulawulwa kwephunga le-chloride hydrogen eliqondile emikhiqizweni yamakha. Amamitha obuningi be-cylindrical anemizimba ye-Hastelloy kanye ne-PTFE lining amelana nokugqwala kwe-acetyl chloride, asekela ukuqapha ukusabela kwamakhemikhali kwesikhathi eside ekwakhiweni kwe-linalyl acetate. Amasignali ahlanganisiwe e-RS485 kanye ne-4-20mA aletha idatha yenqubo ezinzile nenembile ezinhlelweni ze-PLC noma ze-DCS eziphakathi ngaphansi kwezimo zamakhemikhali ezinamandla. Impendulo eqhubekayo engaphakathi ikhulisa ukuguqulwa kwe-feed linalool kanye ne-acetyl chloride, kunciphisa imfucuza yezinto zokusetshenziswa ekukhiqizweni kwe-ester futhi kuthuthukisa njalo ubumsulwa bokukhipha ngaphezu kuka-95%. Ukuqapha kobuningi okuzenzakalelayo, okulandelekayo kusekela ukuhambisana namazinga ekhwalithi ye-GB 29985-2013 ye-linalyl acetate, ngisho nasezinqubweni ezisebenzisa izinyibilikisi eziphilayo ezingenamanzi.
Cela isilinganiso semitha yobuningi be-Lonnmeter ukuze ubhekane nokulawulwa kokusabela kwe-esterification ngamamitha obuningi ekwakhiweni kwe-linalyl acetate. Qinisekisa ukuthi uqapha izinga lokuphakelwa kwe-acetyl chloride ukuze uvimbele ukudluliswa kwe-acetyl chloride kanye nephunga le-hydrogen le-chloride elingafuneki emikhiqizweni yamakha.
