katalyst TPB Triphenyl Bismuth CAS 603-33-8
Trifenili Bismuth
Amabwiriza ngenderwaho y'ubuyobozi: GJB 5276-2003
CAS RN: 603-33-8
1. Imiterere y'umubiri n'imiti:
1.1 Formule ya molekile: C18H15Bi
1.2 Uburemere bwa molekile: 440.3
1.3 Gushonga: Ntishobora gushonga mu mazi, ariko ishongeshejwe muri alukolo idashonga na n-heptane.
1.4 Gukomera no gukora neza: Irakomera ku bushyuhe busanzwe n'umuvuduko usanzwe, ariko ikagira ingaruka ku bushuhe, okisidasiyo ikomeye n'urumuri rukomeye rwa ultraviolet.
Imashini ivura propellant
Triphenylphosphonium (TPB) ikoreshwa nk'ingufu zo gutwika ibintu bishyushye cyane. TPB ishobora kugabanya ubushyuhe bwo gutwika ibintu bishyushye no kugabanya igihe cyo gutwika, kandi nta ngaruka mbi igira ku miterere yo gutunganya ibintu n'imiterere ya mekanike. Igipimo cya TPB ni 0.006%-0.05% by'umusemburo wose, naho igihe cyo gutwika ni 50 °C. Iminsi 7
Katalyst ya polymerization ya monomer
Ikoreshwa nk'ingufu zo gupima acetylene mu buryo bwa cyclooctane tetratin, ingufu zo gupima formaldehyde, ikoreshwa mu gupima polycyclochloride, ingufu zo gupima izindi monomer, nibindi.
