Nitrathoi sellyuloza

Nitrathoi sellyuloza, nit­rosellyuloza, efirhoi murakkabi nitrati sellyuloza; formulai umumiashon[SvN702 (O N) z_g (0N03) kh)p, qimati kh az 1 to 3 tagyir yofta metavonad; massai safedi narmi nakhdor, ki ba sellyuloza shabohat dorad. Khelhoi zerini Nitrathoi sellyuloza ahamiyati ama­li dorand: kolloksilin (10,7—12,2% N dorad), piroksilin № 1 (13,0 — 13,5%’N dorad), piroksilin № 2 (12,2—12,5% N dorad). Zichii Nitrathoi sellyuloza 1580—1650 kilogramm/metr3; darajai miyonai polimerzasiyai kolloksilin 150— 600 (massai moliash 37500—150000), pi­roksilinho 1000—2000 (massai molii 250000—500000) meboshad.

Halshavandagii Nitrathoi sellyuloza ba mikdori nitrogen vobasta ast; hamai namudhoi Nitrathoi sellyuloza dar aseton nagz hal meshavand, dar ob, benzol, chorkhloridi karbon, benzin boshad, hal nameshavand; az tasiri kislotahoi serobi gayriorganiki gidroliz va az tasiri ishqorho vayron meshavand Tajziyai Nitrathoi sellyuloza dar harorati 40—60° Selsiya cap shuda, bo afzudani garmi bo tarkish yo afruzish ba anjom merasad. Nitrathoi sellyulozai tekhnikiro dar 20—40% ob yo spirt nigoh medo- rand. Tainoti istifodai Nitrathoi sellyulozaro az rui foizi nitrogen muayyan me­kunand.

Kolloksilinro dar istehsoli sel­luloid, nitrolakho, nitrokleyho, nitroemalho va piroksilinhoro dar istehsoli borut, dinamit va digar moddahoi tarkanda kor mefarmoyand. Nmtrathoi sellyuloza tez dargiranda meboshand, binobar in alhol dar istehsolot onhoro beshtar ba asetathoi sellyulo­za va polimerhoi sintezi ivaz me­kunand.
