I-11-Hydroxyundecanoic Acid (CAS#3669-80-5) Intshayelelo
I-11-HYDROXYUNDECANOIC ACID yinto eqinileyo emhlophe, enyibilikayo kwi-alcohols nakwi-organic solvents, kwaye inyibilika kancinane emanzini. Indawo yayo yokunyibilika ikuluhlu lwama-52-56 degrees Celsius. I-compound yintlukwano ye-asidi enamafutha kunye neqela le-hydroxyl kunye ne-carbon chain structure.
Sebenzisa:
I-11-HYDROXYUNDECANOIC ACID isetyenziswa kakhulu kwishishini lemichiza. Isetyenziswa ngokuqhelekileyo ekudityanisweni kwee-surfactants, ii-polymers, i-lubricant, i-thickeners kunye ne-emulsifiers. Ukongeza, ingasetyenziselwa ukulungisa iikhompawundi ze-organosilicon kunye ne-dayi ephakathi.
Indlela:
Kukho iindlela ezininzi zokudibanisa i-11-HYDROXYUNDECANOIC ACID, enye efunyenwe yi-ester hydrolysis reaction ye-Undecanoic ACID kunye ne-sodium hydroxide kwisisombululo se-ethanol, i-acidification elandelayo inika i-11-HYDROXYUNDECANOIC ACID. Ezinye iindlela zibandakanya ukuphendula kwe-oxidation, ukunciphisa i-carbonyl, kunye nokunye okunjalo.
Ulwazi ngoKhuseleko:
I-11-HYDROXYUNDECANOIC ACID ngokuqhelekileyo ithathwa njengento ekhuselekileyo, kodwa iinkqubo ezifanelekileyo zokhuseleko kufuneka zilandelwe. Xa uphatha le ngqungquthela, kucetyiswa ukuba unxibe iiglasi zokukhusela, iiglavu kunye neengubo zebhubhoratri. Kuphephe ukuphefumla umphunga wayo kunye nokuchukumisa ulusu. Idatha yokhuseleko lwekhompawundi kufuneka iqondwe ngokweenkcukacha phambi kokusetyenziswa, kwaye igcinwe kwaye iphathwe phantsi kweemeko ezifanelekileyo. Ukuba kukho nakuphi na ukungakhululeki, funa unyango ngokukhawuleza.
