Sodium carboxymethyl selile yamashanyarazi mumazi

Intangiriro

Carboxymethyl selulose (CMC) ni ubwoko bukomoka kuri selile bukoreshwa cyane mu nganda zitandukanye, harimo ibiryo, imiti, impapuro, n'imyenda. Ni polymer yamashanyarazi ikorwa mugukora selile hamwe na sodium monochloroacetate cyangwa sodium dichloroacetate imbere ya alkali. CMC ni ifu yera, idafite impumuro nziza, idafite uburyohe bukoreshwa nkibikoresho byibyimbye, stabilisateur, emulifiseri, hamwe nuguhagarika ibicuruzwa mubicuruzwa bitandukanye. Irakoreshwa kandi nka binder muri tableti na capsules, kandi nkamavuta yo gukora ibinini.

Ubushobozi bwa CMC mumazi biterwa nibintu byinshi, harimo urugero rwo gusimbuza (DS), uburemere bwa molekile, na pH. Urwego rwo gusimbuza ni umubare wamatsinda ya carboxymethyl kumurwi wa anhydroglucose (AGU) mumurongo wa polymer, kandi mubisanzwe bigaragazwa nkijanisha. Iyo DS iri hejuru, niko hydrophilique CMC irushaho gukomera mumazi. Uburemere bwa molekuline ya CMC nabwo bugira ingaruka ku gukomera kwayo mumazi; uburemere buke bwa molekuline bukunda kuba bworoshye. Hanyuma, pH yumuti irashobora kandi kugira ingaruka kubisubizo bya CMC; indangagaciro za pH zikunda kongera ubukana bwa CMC.

Ubushobozi bwa CMC mumazi nabwo bugira ingaruka no kuba hari ibindi bintu mubisubizo. Kurugero, kuba electrolytite nka sodium chloride ya sodium irashobora kugabanya ubukana bwa CMC mumazi. Mu buryo nk'ubwo, kuba hari ibishishwa kama nka Ethanol birashobora kandi kugabanya ubukana bwa CMC mumazi.

Ubushobozi bwa CMC mumazi burashobora kugenwa mugupima ubunini bwa CMC mugisubizo ukoresheje spekitifotometero. Ubwinshi bwa CMC mubisubizo burashobora kugenwa mugupima kwinjiza igisubizo kumuraba wa 260 nm. Kwinjira bigereranywa no kwibanda kwa CMC mugisubizo.

Muri rusange, CMC irashonga cyane mumazi. Ubushobozi bwa CMC mumazi bwiyongera hamwe no kwiyongera kurwego rwo gusimburwa, uburemere bwa molekile, na pH. Ubushobozi bwa CMC mumazi nabwo bugira ingaruka no kuba hari ibindi bintu mubisubizo.

Umwanzuro

Carboxymethyl selulose (CMC) ni polymer-eregiteri ya polymer ikoreshwa cyane mubikorwa bitandukanye. Ubushobozi bwa CMC mumazi biterwa nibintu byinshi, harimo urugero rwo gusimbuza, uburemere bwa molekile, na pH. Muri rusange, CMC irashonga cyane mumazi, kandi gukomera kwayo kwiyongera hamwe no kwiyongera kurwego rwo gusimburwa, uburemere bwa molekile, na pH. Ubushobozi bwa CMC mumazi nabwo bugira ingaruka no kuba hari ibindi bintu mubisubizo. Ubwinshi bwa CMC mubisubizo burashobora kugenwa mugupima kwinjiza igisubizo kumuraba wa 260 nm.
