Intshayelelo

I-Triethyl citrate lulwelo olungenambala kunye nencasa yelamuni. Oku kulandelayo sintshayelelo kwiipropati zayo, ukusetyenziswa, iindlela zokuvelisa kunye nolwazi lokhuseleko:

 

Umgangatho:

- Imbonakalo: Ulwelo olungenambala

- Ukunyibilika: Ukunyibilika emanzini kunye nezinyibilikisi eziphilayo

 

Sebenzisa:

- Kumashishini, i-triethyl citrate ingasetyenziswa njengeplastiki, iplastiki kunye ne-solvent, njl

 

Indlela:

I-Triethyl citrate ilungiswa ngokusabela kwe-citric acid kunye ne-ethanol. I-asidi ye-citric ngokuqhelekileyo i-esterified kunye ne-ethanol phantsi kweemeko ze-acidic ukuvelisa i-triethyl citrate.

 

Ulwazi ngoKhuseleko:

- Ithathwa njengekhompawundi enetyhefu ephantsi kwaye ayinabungozi kangako ebantwini. Ukungeniswa kweedosi ezinkulu kunokubangela ukuphazamiseka kwesisu, okunje ngeentlungu zesisu, isicaphucaphu, kunye norhudo.

- Xa usebenzisa i-triethyl citrate, izilumkiso ezifanelekileyo ezifunekayo kufuneka zibekwe kwimeko-nge-case basis. Landela ukuphathwa ngendlela eyiyo kunye nemilinganiselo yokuzikhusela ukuze uqinisekise ukusetyenziswa ngokukhuselekileyo.
