Mapulogalamu

Ma diamondi ndi gulu lofunika kwambiri la mankhwala omwe amagwiritsidwa ntchito kwambiri ngati zinthu zopangira, zinthu zapakati kapena zinthu zina. Mwachitsanzo, ma diamondi ndi mayunitsi ofunikira popanga polyamide ndi zina zomwe zimapangitsa kuti ma condensation polymerization ayambe kugwira ntchito. N,N-dimethyl-Chemicalbook1,3-diaminopropane (DMAPA) ndi chinthu chofunikira kwambiri, chomwe chimagwiritsidwa ntchito mwachitsanzo pokonza mafuta opangira mafuta m'mafakitale. Kuphatikiza apo, DMAPA imagwiritsidwa ntchito ngati chinthu chopangira ma coagulants ndipo yokha iyenera kukhala ndi mphamvu zotsutsana ndi dzimbiri.

Katundu wa Mankhwala:

Madzi opanda mtundu komanso owonekera bwino. Amasungunuka m'madzi ndi zinthu zachilengedwe zosungunulira.

Chizindikiro cha refractive n20/D1.435 (lit.)

Malo owunikira 90°F

Malo osungiramo zinthu Sungani pansi pa +30°C.

Kagwiritsidwe:

Amagwiritsidwa ntchito kwambiri popanga zinthu zodzikongoletsera, monga palmitamide dimethylpropylamine, cocamidopropyl betaine, mink oil amidopropylamine, ndi zina zotero.

Njira yopangira:

Gwiritsani ntchito dimethylaminopropionitrile [1738-25-6] ngati zinthu zopangira, hydrogenate ndi methanol pamaso pa Ni-Al catalyst, kenako sefani ndikusungunula kuti mupeze 3-dimethylaminopropylamine yomalizidwa. Kuyera kwa chinthu chomwe mwapeza kumatha kufika pa 99%, ndipo tani iliyonse ya chinthucho imadya 1150kg ya dimethylaminopropionitrile.
