Payvasthoi organikii silisiy

Payvasthoi organikii silisiy, payvasthoi khimiyavie, ki dar molekulaashon bandi silisiy- karbon (Si—S) dorand. Payvasthoi organikii silisiy ba guruhhoi zerin chudo meshavand; 1) organogalogensilnho yo alkil (aril) galogenenlanho R_nSiX4__u; organogidridgalogensilanho R_nSiH_mX4(_{n +} sh) (X —aksar vaqt Cl); organoasioksisilanho R_nSi(0R^/)4__n; organoasiloksisilanho R_nSii(OCOR^,)4__n; organoaminosilanho R_nSi(NH₂)4__n. 2) Organosilanho R_nSi>H4__n. 3) Organosiloksanho R₃SiOSiR₃, R₃SiOSi (R₂)OSiR₃ va gayra; siklosiloksalho (R₂SiO) n (n = 3—10, aksar 3—-4). 4) Payvasthoi geterosikli, masalan, dimetilsilasiklobutan

Payvasthoi organikii silisiyro dar sanoat asosan az tasiri bevositai alkilkhloridho (yo arilkhloridho) ba silisiy dar ishtiroki mis, inchunin reaksiyam payvasthoi metalloorganiki, kondensasiyai termi, degndrokondensatsiya va gayra hosil mekunand.

Aksari Payvasthoi organikii silisiy  moei berang (tanho bazeashon masalan, siklosiloksanho moddahoi kristalliand) buda, az tasiri garmi vay­ron nameshavand. Onho dar karbogid- ridho, karbogidridhoi khloronidashuda, efirho va digar halkunandahoi organiki nagz hal meshavand. Payvasthoi organikii silisiyro dar istehsoli kauchuk va mahlulhoi silisiyorganiki, tayyor namudani qolabhoi rekhtagari va gayra is­tifoda mebarand.
