Izicelo

Ama-diamine ayisigaba esibalulekile samakhemikhali asetshenziswa kabanzi njengezinto zokusetshenziswa, izinto eziphakathi noma imikhiqizo. Isibonelo, ama-diamine ayiyunithi ebalulekile yesakhiwo ekuhlanganisweni kwe-polyamide kanye nezinye izindlela zokupholisa i-condensation. I-N,N-dimethyl-Chemicalbook1,3-diaminopropane (DMAPA) iyi-intermediate ebalulekile, esetshenziswa isibonelo ekulungiseleleni izinsimbi zokugcoba zezimboni. Ngaphezu kwalokho, i-DMAPA isetshenziswa njengezinto zokusetshenziswa zokulungiselela ama-coagulant futhi yona ngokwayo kufanele ibe nezakhiwo zokulwa nokugqwala.

Izakhiwo Zamakhemikhali:

Uketshezi olungenambala nolubonakalayo. Luncibilika emanzini nasezincibilikisini eziphilayo.

Inombolo ye-CAS 109-55-7

Ifomula yama-molecule C5H14N2

Isisindo sama-molecule 102.18

Inombolo ye-EINECS 203-680-9

Iphuzu lokuncibilika -60°C

Iphuzu lokubila 133°C (elikhanyayo)

Ubuningi 0.812g/mL ku-25°C (ngokukhanya)

Inkomba yokubuka n20/D1.435 (ekhanyayo)

Iphoyinti lokuphazima 90°F

Izimo zokugcina Gcina ngaphansi kuka-+30°C.

Ukusetshenziswa:

Isetshenziswa kabanzi ekwenziweni kwezinto zokusetshenziswa zokuhlobisa, njenge-palmitamide dimethylpropylamine, i-cocamidopropyl betaine, i-mink oil amidopropylamine, njll.

Indlela yokukhiqiza:

Sebenzisa i-dimethylaminopropionitrile [1738-25-6] njengezinto zokusetshenziswa, i-hydrogenate kanye ne-methanol lapho kukhona i-Ni-Al catalyst, bese uhlunga bese uhlanza ukuze uthole umkhiqizo oqediwe we-3-dimethylaminopropylamine. Ubumsulwa bomkhiqizo otholiwe bungafinyelela ngaphezu kwama-99%, futhi ithani ngalinye lomkhiqizo lidla ama-1150kg e-dimethylaminopropionitrile.
