Theko e Ntle ea Moetsi Pentamethyldipropylenetriamine (PMDPTA) CAS:3855-32-1

tlhaloso e khutšoanyane:

PMDPTA ke sesebelisoa sa ho lokisa foam/gel se nang le monko o tlase, se ka sebelisoang foam e bonolo ea polyurethane ea mofuta oa polyether, li-bubble tse thata tsa polyurethane le likhomaretsi tse koahelang. PMDPTA e sebelisoa haholo-holo foam ea HR ea hlobo e batang. PMDPTA e bitsoa five-base di-propyleneramine, e nang le mefuta e mengata ea ts'ebeliso lifomong tse fapaneng tse bonolo le tse thata. PMDPTA e ka fana ka karabelo e leka-lekaneng ea ho qala le karabelo ea gel, 'me ea eketsa karabelo ea foam le nako ea karabelo ea gel. Sesebelisoa sena sa ho lokisa foam se ke ke sa sebelisoa feela se le seng, empa hape se ka arolelanoa le li-catalyst tse ling le li-agent tse thusang. PMDPTA e ka qhibilihisoa ka polyol ea polyether.

E qhibiliha habonolo lihlapollong tse ngata. Tekanyo ea karabelo ea foam le gel. Melemo e sebelisoa foam e bonolo e nang le li-block, e ka qobang ho petsoha le lesoba la foam, e nang le ts'ebetso e ntle ea ho phahamisa. Ntlafatsa bokhoni ba ho sebetsa, mamello le ts'ebetso ea ho phekola holim'a foam e thata. Ntlafatsa lesoba le phahameng la polasetiki e bonolo ea foam.

Thepa ea thepa: ntlha ea ho belisa: 102 ° C / 1mmHg, bongata: 0,83 g / cm3, index ea refractive: 1.4450 ho isa ho 1.4480, ntlha ea flash: 92 ° C, coefficient ea asiti (PKA): 9.88 ± 0.28 (E bolela esale pele). E sebelisoa haholo bakeng sa li-phenol tse qhibilihang tsa alkaline, 'me e boetse e sebelisoa bakeng sa li-inter-phenylphenols, jj., 'me hangata e sebelisoa e le li-catalyst liketsong tsa esterization le dehydration; dae intermediate
