Iyini i-Triacetin futhi Ungayithenga Kanjani I-Triacetin?

Iyini i-Triacetin?

I-Triacetin iyinhlanganisela ye-organic, ifomula yamangqamuzana ye-C9H14O6. Iwuketshezi olunamafutha angenambala, olunganuki, oluxubene ne-ethanol, i-ether, i-chloroform ne-benzene, futhi luncibilika kancane emanzini ne-carbon disulfide.

I-Triacetin iyi-plasticizer evumelana nemvelo engenawo ama-phthalates. Isetshenziselwa kakhulu amathiphu okuhlunga ugwayi okuyi-plasticizer ye-cellulose diacetate, ebuye isetshenziswe ku-flavour, i-cosmetics fixative. Ngaphandle kwalokho, ingasetshenziswa njenge-plasticeizer nezincibilikisi zoyinki wokuphrinta, i-nitrocellulose, i-cellulose acetate, i-ethyecellulose ne-ellulosi acetate butyrate.

Yiziphi izakhiwo zamakhemikhali ze- Triacetin?

I-Triacetin iwuketshezi olunamafutha angenambala, olunganuki. Ixubene ne-ethanol, i-ether, i-benzene, i-chloroform nezinye izincibilikisi eziphilayo, ezincibilika ku-acetone, ezingancibiliki kuwoyela wamaminerali. Incibilika kancane emanzini.

I-Triacetin inephunga elibi kakhulu, elinezithelo. Inokunambitheka okuthambile, okumnandi okubabayo ngaphezu kuka-0.05%.

I-Triacetin isetshenziselwa ini?

I-Triacetin isebenza ekudleni njenge-humectant ne-solvent.

I-Triacetin isetshenziselwa izimonyo, iziqholo, nokudla njengesixazululi nanjengesixazululi ekwakhiweni kwamakha nama-flavour.

Njengesixazululi ku-perfumery; i-solvent ekwenzeni i-celluloid, amafilimu ezithombe. I-Technical triacetin (inhlanganisela ye-mono-, di-, nenani elincane le-triacetin) njengesixazululi sikadayi abayisisekelo, ikakhulukazi i-indulines, ne-tannin ekudayeni.

I-Triacetin isetshenziswa kakhulu njenge-plasticizer ye-hydrophilic kukho kokubili i-polymeric esekelwe emanzini kanye ne-solvent yama-capsules, amaphilisi, ubuhlalu, nama-granules.

Ithini indlela yokukhiqiza ye- Triacetin?

I-Triacetin ilungiswa nge-esterification ye-glycerin ene-acetic anhydride.

I-Triacetin ingatholakala ku-esterification ye-glycerol ne-acetic acid. Ngemuva kokushisa kuqala i-glycerol iye ku-50-60℃, engeza i-acetic acid, i-benzene ne-sulfuric acid. Shisisa futhi ushukumise ukuze ukhiphe amanzi emzimbeni, bese ugaya kabusha i-benzene. Bese wengeza i-acetic anhydride ukushisisa amahora angu-4. Ngemva kokupholisa, ingxube iye yancishiswa ngo-5% we-sodium carbonate kuya ku-pH 7, futhi ungqimba olungahluziwe lomiswa futhi uwoyela ongahluziwe womiswa nge-calcium chloride. Distill ngaphansi kwengcindezi eyehlisiwe, qoqa ingxenyenamba engu-128-131℃(0.93 kPa), okuyi-glycerol triacetate.

Yiziphi izinyathelo zosizo lokuqala ngemuva kokuxhumana ne-Triacetin?

Uma ehogelwe

Uma uphefumula, hambisa umuntu emoyeni omusha. Uma ungaphefumuli, nikeza ukuphefumula okwenziwa.

Uma kwenzeka ukuthintana kwesikhumba

Geza ngensipho namanzi amaningi.

Uma uthintana namehlo

Hlanza amehlo ngamanzi njengesinyathelo sokuzivikela.

Uma igwinywe

Ungalokothi unikeze noma yini ngomlomo kumuntu oqulekile. Hlanza umlomo ngamanzi.

Iyini i-solubility ye-Triacetin?

I-Triacetin inyibilika emanzini, ihlangana ne-ethanol (amaphesenti angama-96) kanye ne-toluene.

Ithini p profile si-afety ye - Triacetin ?

Iso elicasulayo. Iyasha uma ichayeke ekushiseni, elangabini, noma kuma-oxidizers anamandla. Ukulwa nomlilo, sebenzisa igwebu lotshwala, amanzi, i-CO2, ikhemikhali eyomile. Uma ishiselwa ukuze ibole ikhipha intuthu emuncu kanye nentuthu ecasulayo.

Siyini isimo sokugcina se-Triacetin?

I-Triacetin izinzile futhi kufanele igcinwe esitsheni esivalwe kahle, esingeyona insimbi, endaweni epholile, eyomile.

Kuyini ukungahambisani kwe- Triacetin?

I-Triacetin ayihambisani nezinsimbi futhi ingase ihlangane nama-oxidizing agents. I-Triacetin ingabhubhisa indwangu ye-rayon.

Ithunyelwa kanjani i-Triacetin ?

Kuma-oda amakhulu:

I-LCL noma i-FCL evela e-Port of Shanghai, e-China. 240kg Iron drum noma 1150kg IBC Tank.

Okwamasampula:

Nge-Fedex noma i-DHL

Ungayithenga kuphi i-Triacetin?

Njengomphakeli ochwepheshe we-Triacetin, i-Ao Zun isebenzela amakhasimende ebhizinisi lomhlaba jikelele. Uma udinga ikhotheshini noma isampula, sicela ukhululeke ukuxhumana nathi nge-imeyili mandy@czqidi.com noma uthumele umlayezo ku-WhatsApp ku- +86- 18452425579.

Ungathanda ukujoyina iqembu lethu?

Uma uba nguzakwethu, akudingekile ukuthi ukhokhe noma yiziphi izindleko ukuze ube nesikhungo esisha senzuzo esisheshayo. Uma usisiza ukuthuthukisa amakhasimende futhi uthole ama-oda, sizokunikeza ikhomishini efanele ngokuya ngenani le-oda. Ngaphezu kwalokho, uma amakhasimende akho esisiza ukuthi sithole ama-oda kwamanye amakhasimende, ungathola ikhomishini kithi. Sibheke ngabomvu koxhumana naye ukuze uthole ukuxhumana okwengeziwe.
