Yintoni Alkyl Ketene Dimer AKD CAS 144245-85-2 ?

I-AKD, enegama lesiTshayina elingu-Alkyl Ketene Dimer, yaqala ushishino ngo-1956 kwaye yayisetyenziswa kuphela kumaphepha akhethekileyo awayefuna ukuphinda-phindwe ubungakanani. Kwiminyaka yakutshanje, iincwadi zeekhemikhali ezisekwe kwiphepha lenkcubeko ziye zatshintshwa zaba yi-AKD yokungathathi hlangothi, kwaye zifumene iindawo ezininzi zokusetyenziswa. Eli nqaku lazisa ulwazi oluphambili lwe-AKD, kuquka iimpawu zayo ezisisiseko, iindlela zokulungiselela kunye neenkqubo, kunye nenkqubela phambili ye-AKD wax, i-emulsion ye-AKD kunye nohlobo lobungakanani bomgangatho we-AKD.

Isicelo

Le mveliso yi-alkyl enone dimer eyenziwe kwi-fatty acids ephezulu (C≥12) nge-acylation kunye ne-dehydrochlorination. Isetyenziswa njengomgubo okrwada we-AKD kunye ne-ejenti yokulinganisa engathathi hlangothi ukuvelisa i-emulsion ye-ejenti yokulinganisa engathathi hlangothi kwipulp.
