Izicelo

Iidiamines ludidi olubalulekileyo lweekhemikhali ezisetyenziswa kakhulu njengezinto eziluhlaza, izinto eziphakathi okanye iimveliso. Umzekelo, iidiamines ziyunithi ezibalulekileyo zesakhiwo ekuhlanganiseni i-polyamide kunye nezinye ii-condensation polymerization reactions. I-N,N-dimethyl-Chemicalbook1,3-diaminopropane (DMAPA) sisixhobo esibalulekileyo esiphakathi, esisetyenziswa umzekelo ekulungiseleleni izinto zokuthambisa kwimizi-mveliso. Ukongeza, i-DMAPA isetyenziswa njengesixhobo esiluhlaza sokulungiselela ii-coagulants kwaye yona ngokwayo kufuneka ibe neempawu zokulwa nokugqwala.

Iipropati zeKhemikhali:

Ulwelo olungenambala nolucacileyo. Lunyibilika emanzini nakwizinyibilikisi zendalo.

Inombolo ye-CAS 109-55-7

Ifomula yemolekyuli C5H14N2

Ubunzima be-molecular 102.18

Inombolo ye-EINECS 203-680-9

Isalathisi sokuhombisa n20/D1.435 (elitha)

Incopho yokutshaza 90°F

Iimeko zokugcina Gcina ngaphantsi kwe-+30°C.

Ukusetyenziswa:

Isetyenziswa kakhulu ekwenzeni izinto zobuhle, ezifana ne-palmitamide dimethylpropylamine, i-cocamidopropyl betaine, i-mink oil amidopropylamine, njl.

Indlela yokuvelisa:

Sebenzisa i-dimethylaminopropionitrile [1738-25-6] njengezinto eziluhlaza, i-hydrogenate kunye ne-methanol xa kukho i-Ni-Al catalyst, uze uyihluze kwaye uyinyibilikise ukuze ufumane imveliso egqityiweyo ye-3-dimethylaminopropylamine. Ubumsulwa bemveliso efunyenweyo bunokufikelela ngaphezulu kwe-99%, kwaye itoni nganye yemveliso itya i-1150kg ye-dimethylaminopropionitrile.
