Selelekela

1,3-Bis[3-(dimethylamino)propyl]urea, e tsejoang hape e le DMTU, ke motsoako oa lintho tse phelang. Se latelang ke selelekela sa sebopeho sa eona, tšebeliso, mekhoa ea tlhahiso le tlhaiso-leseling ea polokeho:

 

Boleng:

- Ponahalo: DMTU ha e na 'mala kapa e bosehla bo bobebe.

- Sollubility: DMTU e na le ho qhibiliha ho hotle ho lihlapolli tse tšoanang tse kang metsi, lino tse tahang le li-ethers.

- Botsitso: DMTU e batla e tsitsitse tlas'a maemo a tloaelehileng a lik'hemik'hale.

 

Sebelisa:

- Urami-agent: DMTU ke ururalizing agent e ka sebelisoang ho kopanya urea gum, spandex fibers le spandex elastane fibers, har'a tse ling.

- Li-retardants tsa malakabe: DMTU e ka sebelisoa e le ntho e thibelang malakabe e se nang halogen linthong tsa maiketsetso tse kang polyamide resin, polyurethane resin, le polyimides ho ntlafatsa thepa ea bona e thibelang malakabe.

 

Mokhoa:

- DMTU e sebetsana haholo le dimethylamine e nang le 3-chloroacetone ho theha mahareng, ebe e kopana le urea ho fumana sehlahisoa sa ho qetela.

 

Lintlha tsa Tšireletseho:

- DMTU ha joale ha e khethoe joalo ka carcinogen kapa ntho e chefo.

- Ha o sebelisa kapa o tšoara li-DMTU, ho lokela ho hlokomeloa ho latela mekhoa e nepahetseng ea ts'ebetso ea ts'ireletso, joalo ka ho thibela ho hema kapa ho kopana le letlalo le mahlo, le ho netefatsa tikoloho ea mosebetsi e nang le moea o motle.

- Ha o boloka le ho tsamaisa, ho kopana le li-oxidants le li-acid tse matla ho lokela ho qojoa ho qoba liketso tse kotsi.
