Kuyini i-Isononanoic Acid?

I-Isononanoic Acid (INA, C₉H₁₈O₂) iyi-C9 carboxylic acid ene-branched chain ekhiqizwa yi-diisobutylene ngenqubo ye-OXO (i-hydroformylation elandelwa yi-oxidation). Isakhiwo sayo esine-branched sinikeza ukuhambisana okuhle kakhulu ne-hydrocarbon-based formulations, izakhiwo ezinhle zokushisa okuphansi, kanye nokuqina okuphezulu kwe-hydrolytic uma kuqhathaniswa nama-fatty acid ane-straight-chain. Ihlobene eduze ne-2-ethylhexanoic acid (C8) kanye ne-neodecanoic acid (C10) ngokwe-chemistry kanye nokusetshenziswa.

Ukukhiqizwa Kosawoti Owomile Ne-Carboxylate

I-Isononanoic acid iguqulwa ibe yi-isononanoates yensimbi — kufaka phakathi i-cobalt, i-manganese, i-zirconium, i-calcium, kanye nosawoti we-zinc — ukuze isetshenziswe njengezinto zokomisa i-oxidative kumapende e-alkyd, i-inki yokunyathelisa, kanye nezingubo zokhuni. Ubude beketanga le-C9 buhlinzeka ngomsebenzi ophezulu we-catalyst endaweni eyomile futhi encibilikayo kahle kuma-aliphatic kanye nama-mineral spirit-based paint media, kanye nokuthambekela okuphansi kokwakheka kwekristalu emazingeni okushisa aphansi.

Izithambisi Zokwenziwa kanye nama-Esters

Ama-ester e-isononanoic acid ane-branched alcohols (njenge-isotridecanol) asetshenziswa njengezinto zokwenziwa zokugcoba kanye namafutha e-compressor anezici ezinhle kakhulu ze-viscosity-temperature kanye nokugeleza okuphansi kwezinga lokushisa. Ama-ester e-Isononanoate asetshenziswa futhi njengabathwali be-solvent ezimonyweni, ekwakhiweni kokunakekelwa komuntu siqu, kanye nanjenge-plasticizers ekusetshenzisweni okukhethekile kwe-polymer.

Iziqinisi zeVinyl kanye Nezimbozo Ezikhethekile

Usawoti we-calcium ne-zinc isononanoate ufakwa kumaphakheji okuqinisa ukushisa koketshezi ukuze kucutshungulwe i-PVC, okunikeza ukubamba okuhle kokuqala kombala kanye nokuqina kokushisa kwesikhathi eside. Ezimbozweni ezikhethekile, ama-alkyd modifiers asekelwe ku-isononanoic acid athuthukisa ukuguquguquka kanye nokunamathela kwe-enamel ebhakiwe kanye ne-coil coating formulations.

Izicelo
