Toluene diisocyanate inowanikwa mumhando mbiri dzeisomeri (2,4-toluene diisocyanate uye 2,6-toluene diisocyanate), dzine hunhu hwakafanana uye mhedzisiro yakafanana. Toluene diisocyanate inogadzirwa mukutengeserana semusanganiswa we80:20 (2,4-toluene diisocyanate:2,6-toluene diisocyanate) wemaisomeri maviri. Pakupisa kwemukamuri, musanganiswa uyu imvura yakajeka, yero yakachenuruka ine hwema hwakapinza, hunorwadza. Inofanira kuchengetwa mufiriji, kure nechiedza nehunyoro mumudziyo wakavharwa zvakasimba munzvimbo isina kusimba. Toluene diisocyanate hainyungudike mumvura uye inogona kusanganiswa nezvinhu zvakawanda zve organic solvents. Toluene diisocyanate inogadzirwa nekuita toluene diamine ne carbonyl chloride (phosgene). Toluene diisocyanate inowanzoshandiswa sechikamu chemakemikari mukugadzira mafoam epolyurethane, elastomers, uye macoatings, pendi, varnishes, waya enamel, sealants, adhesives, uye binders. Inoshandiswawo sechikamu chekubatanidza mukugadzira mapolymers enylon. 2,4-Toluene diisocyanate inoshandiswa sechikamu chemakemikari mukugadzira zvigadzirwa zvepolyurethane, zvakaita semafoam, macoatings, uye elastomers.

Mukugadzira mafoam e polyurethane nedzimwe elastomers.

Asima yebasa ndiyo inonyanya kukonzera chirwere chekufema chinokonzerwa nebasa munyika dzemaindasitiri. Toluene-2,4-diisocyanate (TDI) ndeimwe yeanonyanya kukonzera kufema kunokonzera asthma yebasa.

TDI (toluene diisocyanate) chinhu chakakosha che polyurethane. TDI musanganiswa we2,4-TDI ne2,6-TDI mhando mbiri dze isomers, kusanganisira mhando nhatu dzemhando dzinoshandiswa zvakanyanya: TDI-80/20, TDI-100 neTDI-65/35. Inonyanya kushandiswa mukugadzira foam ye polyurethane inochinjika uye polyurethane elastomer coatings, adhesives, nezvimwewo.

Toluene-2,4-diisocyanate ndeimwe yeisocyanate dzinoshandiswa zvakanyanya. Inoshandiswa mukugadzira furo dzakasimba uye dzinochinjika, elastomers, uye coatings. Pamusoro pekushandiswa kwayo semusanganiswa wakachena, inowanikwa mukutengeserana semusanganiswa we2,4- uye 2,6-isomers (80: 20% uye 65: 35% ratios, zvichiteerana).
