Raws li siv sodium oleate?

Sodium oleate yog ib tug sodium ntsev ntawm oleic acid. Qhia tseem ceeb lub cev thiab tshuaj thaj chaw ntawm lub compound, nws siv.

lub zog

sodium oleate muaj ib tug melting point ntawm 220 degrees Celsius. Nyob rau hauv tej yam kev mob, nws yog ib tug dawb los yog me ntsis daj hmoov, uas yog zoo kawg nkaus soluble nyob rau hauv cov dej thiab kub ethanol. sodium oleate tsis yaj nyob rau hauv ether thiab acetone (ketone). Qhov no compound yog muaj nyob rau hauv cov niaj hnub detergents thiab soaps.

sodium oleate muaj hydrophobic nyhuv. Nws yuav piav los ntawm tus tsim ntawm calcium soaps alkaline Cheebtsam ntawm cov khoom.

cov kev xaiv uas rau

Yuav ua li cas kom tau sodium oleate? Lub inorganic compound uas yog lub hauv paus rau nws tsim - yog sodium hydroxide. Cov ntsev tsim thaum lub sij hawm cov tshuaj cov tshuaj tiv thaiv ntawm lub alkali nrog oleic (organic) acid. Qhov no cov tshuaj tiv thaiv yog reversible, ces tus equilibrium ua haujlwm ntawm lub tsim ntawm cov tshuaj tiv thaiv cov khoom siv concentrated sulfuric acid. Nws cia li nkaum kiag cov dej lwg me me, vim nws yog hygroscopic.

nta zog

Yuav ua li cas yog cov yam ntxwv ntawm sodium oleate? Lub zog ntawm cov compound raug muab faib ua peb pawg:

• Collegiate. Lawv nyob ntawm seb muaj pes tsawg tus molecules. Cov no muaj xws li lub siab txo los yog nce nyob rau hauv kub, ntim.
• Additive. Lawv tshwm sim los ntawm molecular rog, qhia raws li lub sum ntawm lub thaj chaw ntawm pawg ntawm atoms uas yog ib feem ntawm lub lwg me me.
• Design. Cov zog muaj xws li coloring tebchaw, dipole lub sij hawm ntawd.

Sodium oleate yog ib tug colloidal surfactant. Nws muaj kaum yim carbon atoms uas tsim ib tug ruaj khov dispersion ntawm heterogeneous hom system. Qhov no tshuaj compound ntawm lub kev faib txuam nrog cov tshuaj qauv yog ib tug anionic surfactant. Qhov no cov ntaub ntawv uas muaj ib tug ntxuav cov nyhuv, nws siv tau rau hauv cov plaub pab pawg neeg ntawm cov labeling PA Rehbinder. Lub tu nyhuv yog vim cov kev sib cuag ntawm cov aqueous tov ntawm ntsev thiab qhov chaw ntawm cov khib nyiab. Solubilization cov yam ntxwv ntawm sodium oleate yog lub loj complex lub sij hawm nyob rau hauv nws cov detergency.

Micellization yog txawj txheej txheem. Rau nws, tus nqi ntawm cov kev hloov ntawm lub Gibbs zog yog ib tug tsis zoo qhia.

daim ntawv thov

Uas siv sodium oleate? Siv ntawm lub compound raws li ib tug emulsifier, raws li nyob rau hauv nws zoo solubility nyob rau hauv cov dej. Nws yuav siv tau los npaj ruaj khov emulsions ntawm cov roj-dej hom. Tom qab cov kev taw qhia ntawm lub resulting tov ntawm calcium cations muaj tsis insoluble oleate, hloov daim duab nyob rau rov qab tus txheej txheem.

Ua tsaug rau cov muaj nyob rau hauv lub molecule ntawm ib tug organic ntsev moiety tshwm sim benzene adsorption rau ntawm qhov chaw. Tom qab cov kev taw qhia ntawm cov xim mus rau hauv lub emulsion, piv txwv li, sudan III, soluble nyob rau hauv cov uas muaj ntxhiab benzene, yuav ntes tau thiab cov dispersion nruab nrab theem.

Thaum ua yog significantly txo sodium oleate quartz wettability, nws zeta peev xwm. Tsom xam cov dej system ntawm sodium oleate. Tus nqi ntawm nto nro ntawm ntsev ua rau siab ntseeg lawm xwb zawv zawg cheeb tsam mus rau ib tug ntau dua concentration. Qhov no emulsifier ntawm ib tug siab concentration muaj ib tug ncaj qha ntxim rau cov ua npuas ncauj stability.

Nyob rau hauv qhov chaw txheej ntawm cov tshuaj yeeb dej caw concentration yog ntau tshaj no daim duab nyob rau hauv nws lub ntim nyob rau hauv lub kaum ntawm txhiab ntawm lub sij hawm. Sib Nqus kev kho mob ntawm cov aqueous ntsev tov muaj feem xyuam rau nws sorption zog.

Hu nrog sodium oleate ntau yam minerals, uas yog magnetized nyob rau hauv lub slurry tau nyob rau hauv ib tug yuav txo tau ntawm lub tshav kub ntawm tso zis, txo tus kho qhov muag ceev ntawm cov tshuaj.

Summing li, piv txwv li, hais tias cov ntsiab daim ntaub ntawv ntawm cov organic ntsev yuav tsum tau muab sau tseg kev taw qhia ntawm cov tshuaj ntxuav tes. Nws yog ib lub hydrophobic thaj chaw ntawm sodium oleate ua rau nws muaj nrov nyob rau hauv lub kom hniav zoo nkauj lag luam. Colloidal Science News for KIDS, nyob rau lub compound thov piav lub cev thiab tshuaj cov yam ntxwv ntawm cov inorganic thiab organic kev daws teeb meem, lub tseem ntawm lawv ua daim ntawv thov.
