1 3-bis[3-(dimethylamino)propyl]urea（CAS# 52338-87-1)

Folasaga

1,3-Bis [3-(dimethylamino) propyl] urea, e taʻua foi o le DMTU, o se faʻalapotopotoga faʻapitoa. O lo'o ta'ua i lalo se folasaga i lona natura, fa'aoga, auala gaosi ma fa'amatalaga saogalemu:

Tulaga lelei:

- Fa'aaliga: DMTU o se lanu samasama lanumeamata po'o le malamalama.

- Solubility: DMTU e lelei solubility i solvents masani e pei o vai, ava malosi, ma ethers.

- Tulaga mautu: DMTU e fai si mautu i lalo o tulaga masani vailaʻau.

Fa'aaogā:

- Urami-agent: DMTU o se ururalizing agent lea e mafai ona faʻaaogaina e faʻapipiʻi le urea gum, spandex fibers ma spandex elastane fibers, ma isi.

- Fa'avevela afi: E mafai ona fa'aogaina le DMTU e fai ma mea fa'apipi'i e pei o polyamide resins, polyurethane resins, ma polyimides e fa'aleleia atili ai a latou mea e fa'afefe ai le afi.

Metotia:

- DMTU e masani ona tali atu i le dimethylamine ma le 3-chloroacetone e fausia ai se vaeluagalemu, ona tali atu lea ma le urea e maua ai le oloa mulimuli.

Fa'amatalaga Saogalemu:

- DMTU e le'o fa'avasegaina i le taimi nei o se fa'ama'i po'o se mea oona.

- Pe a fa'aogaina pe fa'aaogaina DMTUs, e tatau ona fa'aeteete e mulimulita'ia faiga fa'agaioiga mo le saogalemu, e pei o le puipuia o le manava po'o le fa'afeso'ota'i ma le pa'u ma mata, ma fa'amautinoa se siosiomaga fa'alelei lelei ile galuega.

- Pe a teuina ma felauaiga, faʻafesoʻotaʻi ma vailaʻau faʻamaʻi ma vailaʻau malolosi e tatau ona aloese mai le faʻalavelave mataʻutia.
