Ibi byinjira muburyo bwihariye bwimiti isobanura ubwiza nimiterere ya Milk Lactone.

Dore gusenyuka birambuye:

1. Chimie: Kuki Isomerism ifite akamaro muri Lactone

Kuri lactone nka δ-Decalactone, izina rya "cis" na "trans" ntabwo ryerekeza ku guhuza kabiri (nkuko bikorwa muri molekile nka acide acide) ahubwo ni stereochemie ugereranije na santere ebyiri za chiral kumpeta. Imiterere yimpeta itera ibihe aho icyerekezo cya atome ya hydrogène hamwe nu murongo wa alkyl ugereranije nindege yimpeta itandukanye.

· Cis-Isomer: Atome ya hydrogen kuri atome ya karubone ijyanye kuruhande rumwe rwindege. Ibi birema imiterere yihariye.

· Trans-Isomer: Atome ya hydrogen iri kumpande zinyuranye zindege. Ibi birema imiterere itandukanye, akenshi idakomeye, imiterere ya molekile.

Itandukaniro ryibonekeje muburyo buganisha ku itandukaniro rikomeye muburyo molekile ikorana niyakira, bityo, umwirondoro wacyo.

2. Igipimo muri Kamere na SintetikeAmata ya Lactone

Inkomoko Ibisanzwe cis Isomer Igipimo gisanzwe Trans Isomer Igereranya Impamvu nyamukuru

Kamere (ivuye mu mata)> 99.5% (Muburyo 100%) <0.5% (Trace cyangwa idahari) Inzira ya biosynthesis ya enzymatique mu nka ni stereospecificique, itanga gusa (R) -imikorere iganisha kuri cis-lactone.

Syntetike ~ 70% - 95% ~ 5% - 30% Inzira nyinshi za synthesis ya chimique (urugero, kuva kuri peteroli cyangwa aside aside) ntabwo ari stereospecificique neza, bikavamo kuvanga isomers (ubwoko bwamoko). Umubare nyawo uterwa ninzira yihariye nintambwe yo kwezwa.

3. Ingaruka Zumva: Impamvu cis Isomer ari ngombwa

Ikigereranyo cya isomer ntabwo ari amatsiko yimiti gusa; ifite ingaruka itaziguye kandi ikomeye kumiterere yunvikana:

· Cis-δ-Decalactone: Iyi ni isomer ifite agaciro gakomeye, gakomeye, amavuta, amashaza asa na pome. Nibikorwa-bigira ingaruka kuriAmata ya Lactone.

· Trans-δ-Decalactone: Iyi isomer ifite intege nke cyane, ntiziranga, ndetse rimwe na rimwe ndetse nimpumuro nziza "icyatsi" cyangwa "ibinure". Itanga bike cyane kumurongo wifuzwa kandi irashobora kugabanya cyangwa kugoreka ubuziranenge bwimpumuro nziza.

4. Ibyerekeye Inganda Zihumura & Impumuro nziza

Ikigereranyo cya cis kuri trans isomer nikimenyetso cyingenzi cyubuziranenge nigiciro:

1. Lactone Kamere (kuva Dairy): Kuberako ari cis 100%, zifite impumuro nziza, ikomeye, kandi yifuzwa. Nibindi bihenze cyane kubera inzira ihenze yo kuvana mumata.

2. Lactone yo mu rwego rwohejuru: Lactone: Ababikora bakoresha tekinoroji ya chimique cyangwa enzymatique kugirango bongere umusaruro wa cis isomer (urugero, kugera kuri 95% +). COA ya premium synthique lactone izajya igaragaza ibintu byinshi bya cis. Iki nikintu gikomeye abaguzi bagenzura.

3. Lactone isanzwe ya syntetique: Ibiri munsi ya cis (urugero, 70-85%) byerekana ibicuruzwa bitunganijwe neza. Bizaba bifite intege nke, impumuro nziza kandi ikoreshwa mubisabwa aho igiciro ari umushoferi wibanze kandi impumuro nziza yo hejuru ntabwo ari ngombwa.

Umwanzuro

Muri make, igipimo ntabwo ari umubare uhamye ahubwo ni ikimenyetso cyingenzi cyerekana inkomoko nubwiza:

· Muri kamere, igipimo cyaragabanutse cyane kuri> 99.5% cis-isomer.

· Muri synthesis, igipimo kiratandukanye, ariko ibintu byinshi bya cis-isomer bifitanye isano itaziguye hamwe nimpumuro nziza, karemano, kandi ikomeye cyane.

Kubwibyo, mugihe dusuzuma icyitegererezo cyaAmata ya Lactone, igipimo cis / trans ni kimwe mubyingenzi byingenzi byo gusuzuma kuri Certificat of Analysis (COA).
