I-Emulsion ye-Stearic Acid

(I-Emulsion ye-Stearic Acid)

Ukuveliswa kwangoku kuhambelana ne-emulsion equka ubuncinane enye i-asidi enamafutha kunye ne-agent emulsifying e-soluble yamanzi. Ngokukodwa, ukuveliswa kunika i-emulsion equka ubuncinane i-88% ngobuninzi bamanzi adibeneyo kunye ne-surfactant, apho i-emulsion ihlala kwifom ye-viscous liquid kwaye ayifuni ukulungiswa kwe-pH.

Ukuzinza komzimba we-formulation equkethe i-emulsion yipropati ebalulekileyo. Ngoko ke, ukushisa kwe-solubility kunye ne-phase-transition ye-emulsion ye-stearic acid yafundwa. Ngenxa yale njongo, ukunyibilika kwe-asidi ye-stearic kwatshintshwa ngokubandakanya ezintathu ze-organic amine njenge-counterions. Olu tshintsho lubangele i-emulsion ezinzile.

Impembelelo yesiqulatho se-asidi ye-stearic yaphandwa yi-Fourier transform infrared spectroscopy (FTIR) kunye ne-field emission scanning electron microscopy (FE-SEM). Ukongezelela, iipropati ze-rheological ze-emulsions zichongwe ngeempawu ze-rheological.

Iimpawu ezibonakalayo ze-emulsion ziquka i-viscosity yayo ebonakalayo, i-pH, kunye nobukhulu beglobula yeoli. Ngaphezu koko, i-emulsion ibonakala ngokubakho kwesigaba se-lipophilic esingapheliyo kunye nesigaba se-hydrophilic.

Ukulungiselela i-emulsion, i-stearic acid imisiwe emanzini kwi-concentration ye-5%. Emva koko i-emulsion icutshungulwa ngokusebenzisa izixhobo zokushisa eziphezulu zokushisa. Emva kokuba i-emulsion igqityiwe, ixutywe kunye ne-disperser yokutya.

I-emulsion ye-stearic acid iquka ukunqunyanyiswa kwe-51.3 grams ye-chemically pure stearic acid. Ixutywe kunye nokumiswa kwe-5.60 g ye-calcium oxide kunye ne-300 mL yamanzi ashushu.
