Chaw Tsim Khoom Zoo Tus Nqi Pentamethyldipropylenetriamine (PMDPTA) CAS: 3855-32-1

piav qhia luv luv:

PMDPTA yog ib qho tshuaj catalyst uas tsis muaj ntxhiab tsw qab, uas siv tau rau hauv polyether-hom polyurethane ua npuas mos, polyurethane npuas tawv thiab cov nplaum txheej. PMDPTA tshwj xeeb tshaj yog siv rau hauv pwm txias HR ua npuas. PMDPTA hu ua tsib-base di-propyleneramine, uas muaj ntau yam kev siv rau hauv ntau yam ua npuas mos thiab tawv. PMDPTA tuaj yeem muab kev teb pib sib npaug thiab kev teb gel, thiab txuas ntxiv lub sijhawm ua npuas thiab lub sijhawm teb gel. Cov tshuaj catalyst no tsis yog siv ib leeg xwb, tab sis kuj sib koom nrog lwm cov catalysts thiab cov neeg sawv cev pabcuam. PMDPTA tuaj yeem yaj rau hauv polyether polyol.

Nws yooj yim yaj rau hauv feem ntau cov kuab tshuaj. Ua npuas ncauj thiab gel sib npaug. Cov txiaj ntsig yog siv rau hauv cov npuas mos mos, uas tuaj yeem zam qhov tawg thiab qhov pinhole ntawm cov npuas dej, uas muaj kev ua tau zoo heev. Txhim kho qhov ua tau zoo, kev kam rau siab thiab kev kho qhov chaw ntawm cov npuas dej tawv. Txhim kho qhov siab dua ntawm cov yas ua npuas ncauj mos.

Cov khoom muaj nqis: lub ntsiab lus kub: 102 ° C / 1mmHg, qhov ceev: 0,83 g / cm3, qhov ntsuas refractive: 1.4450 txog 1.4480, qhov taw tes flash: 92 ° C, acidity coefficient (PKA): 9.88 ± 0.28 (Predict). Nws yog siv rau alkaline melting phenols, thiab kuj siv rau inter-phenylphenols, thiab lwm yam, thiab feem ntau yog siv ua catalysts hauv esterization thiab dehydration reactions; dye intermediate
