Umzi-mveliso owaziwayo umgangatho ophezulu weTerephthalaldehyde CAS: 623-27-8

Umzi-mveliso owaziwayo womgangatho ophezulu weTerephthalaldehyde CAS:623-27-8 Umfanekiso ofakiweyo

Inkcazelo emfutshane:

I-Terephthalaldehyde, eyaziwa ngokuba yi-TPA, yialdehyde enuka kamnandi enemichiza ye-C8H6O2.Yikristale eqinileyo engenambala enyibilika ngokulula kwizinyibilikisi zendalo ezifana ne-ethanol kunye ne-acetone.Ngobunzima bemolekyuli ye-134.12 g / mol kunye nendawo yokunyibilika malunga ne-119-121°C, TPA ifanelekile kwizicelo ezahlukeneyo.

Iinkcukacha zeMveliso

Iithegi zeMveliso

Le khompawundi yemisebenzi emininzi isetyenziswa ikakhulu njengeyona nto iphambili ekudityanisweni kweziyobisi, idayi kunye neekhemikhali ezikhethekileyo.Iyinxalenye ebalulekileyo ekwenzeni amayeza afana ne-antihypertensive kunye ne-antifungals.I-TPA idlala indima ebalulekileyo kushishino lwedayi njengoko isisandulela sokwenziwa kwedayi eziqaqambileyo nezihlala ixesha elide zempahla eluka kunye nezinye izinto.Ukongezelela, ingasetyenziselwa ukuvelisa i-resins esetyenziswa ngokubanzi kwi-adhesives kunye neengubo.

Enye yeempawu eziphambili ze-terephthalaldehyde kukucoceka kwayo okuphezulu.Iimveliso zethu zingena kwinkqubo yokucoca ngokungqongqo ukuqinisekisa ukuba azinanto ingcola kunye nezingcolisi, ngaloo ndlela ziqinisekisa ukusebenza okuphezulu kwiinkqubo ezahlukeneyo.Ukongeza, iqela lethu leekhemisti ezinamava lihlala lizama ukugcina imigangatho ephezulu yomgangatho ngexesha lemveliso, okusenza sikwazi ukuhambisa iimveliso ezingaguqukiyo nezithembekileyo.

Siyakuqonda ukubaluleka kozinzo kwihlabathi lanamhlanje, kwaye sinebhongo ukwazisa ukuba i-terephthalaldehyde ihambelana ngokugqibeleleyo nala maxabiso.Iimveliso zethu zenziwa kusetyenziswa iindlela ezinoxanduva lokuqinisekisa impembelelo encinci kokusingqongileyo.Ngaphezu koko, sithobela ngokungqongqo yonke imimiselo yokhuseleko evumela ukuba i-TPA iphathwe kwaye isetyenziswe ngokukhuselekileyo.

Ukuqukumbela, i-terephthalaldehyde iyikhompawundi eguquguqukayo, ecocekileyo kwaye ezinzileyo eye yaguqula amashishini amaninzi.Nokuba ufuna ukuphuhlisa amayeza abukhali, idayi edlamkileyo okanye iingubo ezihlala ixesha elide, iimveliso zethu ze-TPA zisisombululo esifanelekileyo.Sithembe ukuzinikela kwethu ekugqweseni njengoko sibeka phambili umgangatho, uzinzo kunye nokhuseleko kwinqanaba ngalinye lenkqubo yokwenziwa kwemveliso.Sebenzisana nathi namhlanje ukuze uvule amathuba angenasiphelo angaziswa yi-terephthalaldehyde kwishishini lakho.
