Ingasetshenziswa njenge-ejenti elwa namagciwane, i-flame retardant ne-reactant ku-synthesis of monomer. Okwamanje,I-DOPO-HQ isetshenziswa kabanzi njengesizukulwane esisha se-halogen-free, imvelo futhi green ilangabi cishe yizona ezisetshenziswa kakhulu monomer emkhakheni ilangabi cishe yizona ezisetshenziswa kabanzi. I-DOPO-HQis ikakhulukazi esetshenziswa ilangabi cishe yizona ezisetshenziswa kabanzi, ama-polymers asebenzayo akhethekile, i-epoxy resin, izinto ezikhanyayo, izinto eziguquliwe neminye imikhakha. IDohq-po izongena kancane esikhundleni se-epoxy resin njengezinto zokuvikela imvelo. I-Dopo-hq, njengokutholwa kwe-I-DOPO, ingasetshenziselwa ukwelashwa okulangazelela ilangabi i-polyester eqondile, i-polyamide, i-epoxy resin, i-polyurethane nezinye izinto ze-polymer, kanye nama-plastiki wezinto zobuchwepheshe, i-lining laminate yethusi, ibhodi lesifunda nezinye izinto.

Izimo zamagama ze-phosphorus eziqukethe i-flame retardants DOPO-HQ zenziwe zasebenza. I-DOPO-HQ ehlanganisiwe ibonakaliswe yi-1HNMR, FTIR kanye nokuhlaziywa okuyisisekelo. I-Flame retardant rigid polyurethane foam (i-FRPUF) yalungiswa njenge-flame retardant ukutadisha ukubuyiselwa kwayo kwelangabi. Imiphumela ikhombise ukuthi isilinganiso se-DOPO ne-para quinone sasingu-1.1: 1, kanti ukushisa kokuphendula kwakungu-78 C kuma-carbon chloride amane. Ngaphansi kwesikhathi sokuphendula esifanele se-14 h, i-DOPO-HQ yahlanganiswa ngempumelelo. Inqubo ilula, inqubo iphephile, ubumsulwa bomkhiqizo buphezulu, futhi isivuno siphezulu. Ukwengezwa kwe-.DOPO-HQ kungathuthukisa ngokuphawulekayo ukubuyiswa kwelangabi le-foam eqinile ye-polyurethane. Ngemuva kokungeza i-DOPO-HQ engama-45, ibanga lokushisa elima mpo le-foam eqinile ye-polyurethane ingafinyelela ebangeni le-V-0, kanti inkomba ye-oxygen engumkhawulo (i-LOI) ifinyelela kuma-27%, okuyibanga lokuphikisa. Imiphumela ikhombisa ukuthi ukukhishwa kokushisa okuphelele ngokusobala kuncishisiwe futhi indlela yokubuyisela ilangabi isobala
