Ko sodium oleate inoshandiswa sei?

Sodium oleate is sodium salt ye oleic acid. Isu tinoratidza izvo zvinokosha zvemuviri uye makemikari zvinowanikwa mune iyi kanda, munda wekushandiswa kwayo.

Physical properties

Sodium oleate ine nzvimbo yakanyungudutswa ye 220 degrees Celsius. Pasi pemamiriro ezvinhu akaenzana, inenge yakachena kana kuti yakatsvuka, iyo inogadziriswa mumvura, uye inopisa ethyl doro. Sodium oleate haina kusvibiswa mu ether uye acetone (ketone). Ichi chikamu chinosanganiswa mumasikirini emazuva ano uye sesepa.

Sodium oleate ine hydrophobic effect. Inogona kutsanangurwa nekuumbwa kwemashizha e-calcium ne-alkaline zvimwe zvezvinhu.

Sarudzo dzekuwana

Ko sodium oleate inowanikwa sei? Iyo inorganic compound, iyo ndiyo nheyo yekuumbwa kwayo, iyo sodium hydroxide. Munyu inoumbwa nekubatana kwemakemikari e alkali ne oleic (organic) asidi. Izvi zvinodzokorora, saka kuiswa sulfuric acid kunoshandiswa kushandura kuenzana kwekugadzirwa kwezvinhu zvinogadzirwa. Iyo inotora mamolekyuti emvura, nokuti iyo inonzi hygroscopic substance.

Property Features

Chii chinozivikanwa ne sodium oleate? Zvimwe zvechikamu ichi zvakakamurwa kuva mapoka matatu:

• Iyo inotyisa. Vanovimba nenhamba yemamolekoro. Izvi zvinosanganisira kupikisa, kuderera kana kuwedzera mukupisa, ivhu.
• Kuwedzera. Izvo zvinokonzerwa nemakemikari masimba, anotsanangurwa sechiyero chezvinhu zvemapoka emaatomu ayo ari chikamu chema molecule.
• Kuvaka. Izvi zvinosanganisira marara emakemikari, nguva ye dipole.

Sodium oleate inonzi colloidal surfactant. Iyo inosanganisira gumi nemasere emakoromu ematomu, ayo anogadzira gadziriro yakagadzikana yakasanganiswa yemhando yakasiyana-siyana. Izvi zvinokonzerwa nemakemikari zvinoshandiswa sean anionic surfactant nekushambadza kwakabatana nemakemikari ayo. Ichi chinhu chine detergent effect, iyo ndeyeboka rechina maererano neAAP classification. Rebinder. Izvozvo zvinokonzerwa nehutano pakati pemvura yakawanda yeyuyu munyu uye nzvimbo dzakasviba. Solubilization, chimiro che sodium oleate, ndiro izwi guru mumatambudziko ezvinyorwa zvayo.

Micelle maitiro ndiyo nzira yekuzvipira. Kwaari, ukuru hwekushandura muGibbs simba kune maitiro asina kunaka.

Kushanda

Where is sodium oleate used? Kushandiswa kwechigadzirwa ichi se emulsifier kunobva pakubata kwayo kwakanaka mumvura. Nekubatsira kwayo, zvinokwanisika kuwana zvakagadzikana emulsions yemafuta emvura. Mushure mokunge matanho e-calcium cations muchigadzirwa chinoguma, kupera kwe insoluble oleate, iyo inoshandura mufananidzo kune iyo inoshandiswa, inoonekwa.

Nokuda kwekuvapo kwechikafu chechikafu mumamolekoro, kushandiswa kwebhenene kunowanikwa. Mushure mokunge dhayi iri kuiswa mumusasa, semuenzaniso, Sudan III, inogadziriswa neBenene inonhuhwirira, zvinokwanisika kuona iyo kupararira mukati uye chikamu.

Kana ichibatwa ne sodium oleate, mvura yakadzika ye quartz, inokonzerwa nemagetsi, yakanyanya kuderedzwa. Regai tiongorore hurongwa hwemvura-oleate ye sodium. Kukosha kwehupamhi hwemhepo yemunyu kunotungamirira kushanduka munzvimbo yekusagadzikana kune chinangwa chekufungisisa. Iyi emulsifier mumakorokari akakwirira inogadzirisa zvakananga kugadzikana kwehutu.

Muchikamu chepamusoro, huwandu hwehuwandu huno hunopfuura chiyero ichi muhuwandu hwayo ne makumi ezviuru zvezviitiko. Kugadzirwa kwemasvikiro emvura inogadziriswa yemunyu uyu kunokanganisa maitiro ayo.

Kukurukurirana neooramic oleate yemaminerari akasiyana-siyana ari mukumiswa kwemagetsi kunounza kuderedzwa kwekupisa kwekuchenesa kwavo, kuderera kwehuwandu hwemagetsi emhinduro.

Kuti tipfupise, ngatitaurire kuti pakati pezvikamu zvikuru zvekushandiswa kweiyo inoita munyu isumo ye sese. Ndiyo hydrophobic ye sodium oleate iyo yakaita iyo yakatsvaga chikamu muzvigadzirwa zvemuchengetedzo. Chikoro chemakemikari, iyo iyo mutsara inonzi inotsanangurwa, inotsanangura chimiro uye chemikemikirwo maitiro easorganic uye organic solutions, ruzivo rwekushanda kwavo zvinobatsira.
