Uhlalutyo lokuzinza kweziqholo kunye neencasa

Njengezongezo ezibalulekileyo ezisebenzayo kwimveliso yokutya, ukuzinza kweziqholo kunye neencasa kuchaphazela ngokuthe ngqo umgangatho wemveliso kunye namava omsebenzisi. Ukuzinza kweziqholo kunye neencasa kubonakala kakhulu kwiinkalo ezimbini:

Uzinzo lwevumba nevumba

Ukuzinza kwevumba okanye ivumba kubhekisa ekubeni ivumba okanye incasa inokugcina ivumba elifanayo kwixesha elithile naphantsi kweemeko ezithile ngaphandle kotshintsho olukhulu. Olu zinzo lubalulekile kuba ivumba liyinto yokuqala abathengi abanayo ngemveliso. Naluphi na utshintsho olubonakalayo kwivumba luchaphazela ngokuthe ngqo amava abathengi. Izinto ezifana nomlinganiselo wezinto eziguquguqukayo, ukuguquguquka kobushushu bendalo, kunye nokuvezwa emoyeni zichaphazela kakhulu uzinzo lwevumba.

Uzinzo lweempawu zomzimba nezekhemikhali

Ukuzinza ngokwasemzimbeni nangokweekhemikhali kweziqholo kunye neencasa kubhekisa ekubeni iipropati zazo, nokuba zodwa okanye ngaphakathi kwindawo (njengeoyile, utywala, okanye amanzi), azitshintshi na. Ngexesha lokugcinwa okanye ukuvezwa kubushushu, ekukhanyeni, okanye emoyeni, iziqholo kunye neencasa zinokuchaphazeleka yi-oxidation, ukonakala, ukuguquguquka, okanye ukwahlukana, okukhokelela ekwehleni komgangatho wemveliso. Umzekelo, izinto eziqulethe iibhondi ezimbini ezingagcwaliyo zinotyekelo lwe-oxidation xa kukho ioksijini, nto leyo ebangela ukuba ivumba liwohloke.

Izinto Eziphambili Ezichaphazela Uzinzo

Ubushushu

Ubushushu yenye yezona zinto zibalulekileyo ezichaphazela uzinzo. Umzekelo, 2-Methyltetrahydrofuran-3-nye, ukuba igcinwe kubushushu begumbi ixesha elide (endaweni ye-2–8°C ecetyiswayo), inokuba nevumba elimuncu ngenxa yotshintsho kwimilo. Amaqondo obushushu aphezulu akhawulezisa ukuguquguquka kunye neempendulo zeekhemikhali zeekhompawundi ze-organic kwiivumba kunye neencasa, okunciphisa okanye ukutshintsha iinxalenye zazo zevumba. Ngokwahlukileyo koko, amaqondo obushushu aphantsi anokubangela ukuba ezinye iinxalenye ziqine okanye zahlukane, nto leyo echaphazela ukufana.

Uxinzelelo

Kwizikhongozeli ezivaliweyo, utshintsho kuxinzelelo lunokubangela ukulahleka kwezinto eziguquguqukayo. Iziqholo zichaphazeleka kakhulu kukuguquguquka koxinzelelo xa isikhongozeli sivuliwe.

Ubumuncu kunye ne-Alkalinity

Iziqholo kunye neencasa kwiindawo ezine-asidi okanye i-alkaline zinokungena kwi-hydrolysis, i-oxidation, okanye ezinye iimpembelelo zamakhemikhali. Umzekelo, iikhompawundi ezithile ze-ester zi-hydrolyze zibe yi-alcohol kunye ne-asidi phantsi kweemeko ze-alkaline, nto leyo etshintsha iimpawu zevumba lokuqala.

Ixesha

Ukugcinwa ixesha elide kunokubangela ukubola kancinci kancinci okanye ukusebenzisana kwezinto, ingakumbi kwiivumba ezixutyiweyo (iindibaniselwano zeekhompawundi zencasa), ezihlala zinzima ngakumbi. Umzekelo, ubunyulu be I-2,3-hexanedione, ekuqaleni ngaphezulu kwama-98%, inokwehla iye kuma-97.7% emva kweenyanga ezintathu zokugcina (ngokusekelwe kwidatha yovavanyo). Olu tshintsho luncinci kwiinxalenye ezilandelelanayo ngokuhamba kwexesha lunokuchaphazela kakhulu ivumba lilonke.

Ukuthelekisa: Uzinzo lweziqholo ezidityanisiweyo kunye neziqholo ezixutyiweyo

Ukuzinza kweziqholo ezineekhompawundi enye kulula kakhulu ngenxa yokwakheka kwazo okulula, okwenza ukuba iimpendulo zazo kwiimeko zokusingqongileyo zibe lula ukuziqikelela nokuzilawula. Ngokwahlukileyo koko, ukuzinza kweziqholo ezixutyiweyo kuyinkimbinkimbi ngakumbi, njengoko ziqulathe izinto ezininzi ezinokusebenzisana, zenze izinto ezintsha okanye zitshintshe ivumba lokuqala. Ukongeza, ukuhambelana nendawo (umz., iioyile zokuthwala, amanzi, okanye ii-emulsifiers) kufuneka kuqwalaselwe.

Izigqibo kunye neeNgcebiso

Ukuphucula uzinzo lweziqholo kunye neencasa, kubalulekile ukulawula izinto ezingqongileyo ezifana nobushushu, ukukhanya, kunye nokufuma ngexesha lokuveliswa nokusetyenziswa. Ukuphucula iindlela zokwenziwa ukuze kuncitshiswe ukusebenzisana kweekhemikhali phakathi kwezinto nako kubalulekile. Kwindawo yokugcina, kucetyiswa ukusebenzisa izikhongozeli ezivaliweyo, ezingangenisi ukukhanya, nezingenakhemikhali ngelixa kuqhutywa uvavanyo rhoqo ukujonga iimpawu zomzimba nezekhemikhali. Ngokusebenzisa la manyathelo, ukusebenza kweziqholo kunye neencasa kunokwandiswa, kuqinisekiswa amava ahambelanayo nasemgangathweni ophezulu kubathengi.
