Gaas aan midab lahayn oo leh ur caraf udgoon, oo ay fududahay in la dareeriyo. Ku milmay khamriga iyo etherka, iyo sidoo kale ku milma acetone, benzene, dichloroethane, amyl acetate, furfural, iyo xalalka ammonia acetate copper. Aan biyo ku milmin.

1) Dareen-celinta Diels-Alder waxay ku dhacdaa xeryahooda dienophilic-ka-yar ee elektarooniga ah si ay u soo saaraan anthraquinone, kuwaas oo ka-soo-saarkoodu ay yihiin dhexdhexaadiyeyaasha dheeha muhiimka ah, fungicides iyo cayayaanka. (2) Ka fal celi anhydride maleic (oo loo yaqaan anhydride maleic) ka dibna isku ururso si aad u soo saarto tetrahydrophthalic anhydride, kaas oo loo isticmaali karo dawo ahaan iyo balaastiiste loogu talagalay resin polyester iyo epoxy resin. Tetrahydrophthalic anhydride ka dib waxa lagu daray nitric acid si loo helo butane tetracarboxylic acid, kaas oo ah walxo ceeriin ah oo lagu sameeyo rinjiga biyaha ku milma. Sidoo kale, tetrahydrophthalic anhydride waa hydrogenated si ay u soo saarto hexahydrophthalic anhydride, kaas oo loo isticmaali karo wakiilka daaweynta ee resin epoxy. (3) Waxay la falgashaa sulfur dioxide si ay u dhaliso cyclobutene Chemicalbook sulfone, kaas oo markaa loo diyaariyey xal aqueous ah iyo hydrogenated joogitaanka nikkel qalfoofka ah si ay u soo saaraan cyclobutene sulfolane, kaas oo ah dareere xulashada soo saarista hydrocarbon udgoon. Isku dar ah sulfolane iyo diisopropanolamine ayaa loo isticmaali karaa sidii gaas decarbonation ah. (4) Falcelinta telomerization-ka tooska ah ee butadiene ayaa aad waxtar ugu leh warshadaha. Qalabaynta tooska ah ka dib, olefin siddeed kaarboon ah oo silsilad toosan ah ayaa la helayaa, ka dibna hydroformylated iyo hydrogenated si loo helo nonanol, kaas oo leh isticmaalka muhiimka ah ee isku dhafka udgoonka, surfactants, iyo wax lagu daro saliidaha. Isticmaalka isku-dhafan kobalt-ka-soo-qaade ahaan, dhumucdiisa, trimerization-ka iyo tetramerization-ka ayaa ah dhammaan agabka cayriin ee lagu soo saaro aalkolada sare iyo muska makrocyclic.
