Ukuqaliswa kweqela lesibini le-acrylate, i-ethylene glycol diacrylate (No. 15), kwi-2-hydroxyethyl acrylate (No. 11) ayizange izise utshintsho oluninzi kwiphunga.Owokuqala ubonisa iphunga le-mushroom, ngelixa eli libonisa iphunga le-mushroom kunye ne-moss.Nangona kunjalo, kwi-1,2-propanediol diacrylate (No. 16) emva kokuqaliswa kweqela lesibini le-acrylate kwi-acrylic acid-1-hydroxyisopropyl ester (No. 10) / acrylic Acid-2-Hydroxypropyl ester (No. 12) , i-geranium kunye ne-gas lighter iphunga le-monoester yanyamalala kwi-diester, kwaye iphunga legalikhi kunye neglue lenziwa kwi-diester.
Phakathi kwazo zonke ikhonkco elithe ngqo i-n-alkyl acrylates, i-ethyl acrylate (No.Ngokunyuka kobude bomxokelelwane, umgubasi wanda kancinci, kwaye i-n-butyl acrylate (No. 4) yafikelela kwi-2.4ng / lair.Nangona kunjalo, lo mgaqo awusoloko usebenza, kuba umqobo we-methyl acrylate (No.Xa kuthelekiswa nemonomers acrylate ehambelanayo yabo ethyl acrylate (No. 2) kunye propyl acrylate (No. 3), vinyl acrylate (No. 5) kunye propenyl acrylate (No. 6) equlathe iibhondi kabini unsaturated wabonisa 20 kunye 3.5 amaxesha asezantsi ivumba imibundu. .Oku kubonisa ukuba ukungeniswa kweebhondi eziphindwe kabini ezingaxutywanga kwikhonkco lekhabhoni kuya kwandisa kakhulu umyinge wokuvumba kunye nokunciphisa ingcamango yokuvumba.Nangona kunjalo, ukuba i-double bond engahlambulukanga ayikho kwiqela le-terminal, umphumo awubonakali.Ngokomzekelo, i-odor threshold ye-acrylic acid-3- (z) pentene ester (No. 7) kuphela (1.3 ng / lair).
Phakathi kwazo zonke i-alkyl acrylate esters, i-2-ethylhexyl acrylate (No. 13) ibonise i-odor threshold ephezulu ye-20ng / lair, eyayinxulumene nokusebenzisana okubuthathaka phakathi kwe-2-ethylhexyl kunye ne-odor acceptor ngenxa yempembelelo ye-steric yokuthintela i-2-ethylhexyl.Umda wevumba eliphezulu le-2-ethylhexyl acrylate kunye nokusetyenziswa kwayo ukuphucula ukuthamba kunye nokuguquguquka kwe-acrylic resin dispersion yenza ukuba ilungele ukusetyenziswa njenge-additive okanye i-comonomer kwiingubo eziphantsi zevumba kunye ne-adhesives.Nangona kunjalo, ukudibana kwexesha elide kunye ne-2-ethylhexyl acrylate kunokukhokelela kwi-tumor okanye umhlaza, kwaye i-odor threshold yayo ephezulu ingaba yinto engafanelekanga, kuba ayiyi kubonwa ngumzimba womntu.
I-odor threshold ye-acrylate equkethe i-cyclopentane kunye ne-cyclohexane (iNombolo ye-17 kunye ne-18) ayikho ngaphantsi kwe-non-cycloalkyl enenani elifanayo le-athomu ye-carbon.Ngelo xesha, i-odor threshold of cyclopentane acrylate (No. 17) yayingamaxesha angama-30 aphezulu kune-cyclohexane acrylate (No. 18).
Kwi-2-hydroxyethyl acrylate (No. 11) kunye ne-2-hydroxy-n-propyl acrylate (No. 12), ukuqaliswa kwe-hydroxyl kwisakhiwo kuphuculwe kakhulu i-odor threshold, eyayiyi-178 kunye ne-106ng / lair ngokulandelanayo, eyenza i-odor yabo. ivumba liphantsi kakhulu.Umkhwa ofanayo unokubonwa kwintlukwano ye-odor threshold phakathi kwe-sec butyl acrylate (No. 8) kunye ne-1-hydroxyisopropyl acrylate (No. 10).
Ngokusungulwa kwe-SEC butyl, i-odor threshold of acrylate yancitshiswa kakhulu ibe yi-0.073ng / lair kuphela, ibonisa i-odor threshold ephantsi phakathi kwazo zonke i-alkyl acrylates, oko kukuthi, iphunga elinamandla.
Phakathi kwee-monomers ze-20 ezinqunywe, i-2-methoxyphenyl acrylate (No.Umda wevumba we-2-methoxyphenyl ester, esetyenziswa ngokubanzi njengesiseko kwishishini lokutya kunye ne-flavour industry, yi-0.088ng/lair.Oku kubonisa ukuba ii-esters ezimbini ezine-2-methoxyphenyl isakhiwo zidlala indima kwi-amkeli yevumba elifanayo.
Patrick Bauer kunye nabanye 'uphando kwezi 20 monomers acrylate lubonise ukuba monomers elifutshane chain ubukhulu becala wabonisa ivumba efana sulphur, igesi lighter kunye ikonofile, ngelixa monomers chain elide ikakhulu ebonisa ivumba efana amakhowa, geraniums kunye neminqathe.Zonke iimonomers ze-acrylate zibonise umda wevumba eliphantsi, oko kukuthi, zonke zinevumba elikhulu.Imida yokuvumba ye-SEC butyl acrylate kunye ne-2-methoxyphenyl acrylate yayiphantsi kakhulu, ibonisa iphunga elinamandla.I-2-hydroxyethyl acrylate kunye ne-2-hydroxypropyl acrylate yayineyona ndawo iphakamileyo yokuvumba kunye nevumba eliphantsi.
