Njengoko kusetyenziswa sodium oleate?

Sodium oleate i ityuwa sodium of oleic acid. Chonga iimpawu eziphambili emzimbeni eekhemikhali compound, ukusetyenziswa kwayo.

iipropati ngokomzimba

sodium oleate has indawo yokunyibilika degrees 220 Celsius. Phantsi kweemeko eziqhelekileyo, le ngumgubo omhlophe okanye omthubi kancinane, nto leyo ezinyibilikayo ngokupheleleyo emanzini kunye ethanol ashushu. sodium oleate ayichithwanga kaEtere kunye acetone (ketone). Le compound ibandakanyiwe iisepha mihla kunye iisepha.

sodium oleate ngandlela hydrophobic. Kokuba kuchazwe yi ukuyilwa kumacandelo calcium ezinjengeesepha ze-alkali ze mbandela.

ongakhetha kuzo

Indlela ukufumana sodium oleate? Umchiza ezingaphiliyo leyo isiseko lasungulwa - na sodium hayidroksayidi. Ityuwa wambumba ngexesha umchiza abasabela ngayo kwealkali kunye oleic (organic) asidi. Siyaqondakala isizathu ingathityazwa, ngoko ke shift kuvuselele ukuya ukuyilwa kwemveliso indlela kukudliwa sulphuric acid wamandla. It isiginci molekyuli amanzi, ekubeni hygroscopic.

iimpawu izakhiwo

Ziintoni iimpawu sodium oleate? Iimpawu compound bohlulwa babe ngamaqela amathathu:

• Collegiate. Bona kuxhomekeka kwinani iimolekyuli. Ezi ziquka ukuncipha okanye ukunyuka kwamaqondo obushushu koxinzelelo, umthamo.
• Additive. Bona zibangelwa amandla emolekyuli, wavakalisa njengoko udibaniso iimpawu amaqela athom eziyinxalenye yale iimolekyuli.
• Design. Le propati ziquka iikhompawundi umbala, mzuzu dipole.

Sodium oleate i lunezinto colloidal. It iqulathe athom elinesibhozo carbon bayila usasazeko ezinzileyo inkqubo uhlobo owahlukeneyo. Le compound eekhemikhali ulwahlulohlulo ezinxulumene isakhiwo yemichiza i lunezinto anionic. Le nto iye ibe nefuthe ukuhlamba, sisebenza kwiqela yesine nokufaka PA Rehbinder. Isiphumo wokucoca kungenxa kumfowunelwa phakathi isisombululo zolwelo ye ityuwa kunye evele eziqinileyo. Solubilization uphawu sodium oleate ligama entsonkothileyo enkulu detergency yayo.

Micellization inqubo kulogo. Ngokuba kuye, imali yokutshintsha ye-eneji Gibbs luphawu negative.

isicelo

Esebenzisa sodium oleate? Sebenzisa le umchiza njengento emulsifier, ngokusekelwe ukunyibilika kwayo okulungileyo emanzini. Ingasetyenziswa ukulungiselela emulsions nzile uhlobo oyile-manzi. Emva kokuba ukuqaliswa onesiphumo ngesisombululo ukuse- calcium kukho ilahleko oleate ezingenakunyibilika, litshintsha picture ngenkqubo umva.

Ngenxa phambi kwesi molecule i moiety yetyuwa ephilayo kwenzeka benzene adsorption phezu komhlaba. Emva Ukuqaliswa idayi kulo emulsion, umzekelo, Sudan III, enyibilikayo benzene esinevumba elimnandi, kungabonwa kwaye eziziintsali kwisigaba esiphakathi.

Xa unyango sodium oleate eliphantsi kakhulu wettability zwi, amandla ayo zeta. Hlaziya inkqubo amanzi sodium oleate. Ixabiso lika kumphezulu ukuqina yetyuwa kukhokelela yokungasebenzi ngokokushiyana mmandla ube ingqalelo ephakamileyo. Le emulsifier kwi enamandla aphezulu nefuthe ngqo kuzinzo amagwebu.

Kumphezulu inwebu xi kweziyobisi mkhulu kunale kweli nani umthamo yayo kumashumi amawaka amaxesha. unyango Magnetic yezisombululo ityuwa zolwelo kuchaphazela iipropati yayo sorption.

Qhagamshelana ne sodium oleate izimbiwa ezahlukeneyo, ezo magnetized kwiziphumo oluludaka ukwehla kwe ekufudumaleni xa belele, nokunciphisa ingxinano woqondo yezisombululo.

UPawulos, umzekelo, ukuba phakathi izicelo eziyintloko ityuwa ephilayo kufuneka kuqwalaselwe ukuqaliswa isepha. Yeyona iimpawu hydrophobic sodium oleate bamenza nto ithandwa kushishino mhle. chemistry Colloidal, apho ezimbaxa ibango ichaza iimpawu zomzimba kunye eekhemikhali izisombululo ezingaphiliyo organic, ingakumbi isicelo wabo.
