The influence of bonding agents in improving interactions in composite propellants, determined using the FTIR spectra

Abstract

Bonding agents synthesized in this research are 1, 3, 5-trisubstituted isocyanurates (substituents: 2-hydroxyethyl, 3-hydroxypropyl, 2-hydroxypropyl and 2, 3-epoxypropyl). All syntheses reactions were carried out according to a modified literature procedure. All the synthesized isocyanurates were identified by their melting point and FTIR, 1H NMR and UV spectroscopic data. The Fourier transform infrared spectrophotometry was also used to study the interaction between ammonium perchlorate, hydroxyl terminated poly(butadiene), carboxyl terminated poly(butadiene), cyclotetramethylenetetranitramine, tris[1-(2-methyl)aziridinyl]phosphine oxide and the compounds synthesized in this work. The results show that 1,3,5-tri(2-hydroxyethyl)isocyanurate is a universal bonding agent for the ammonium perchlorate/carboxyl terminated poly(butadiene)/cyclotetramethylenetetranitramine composite propellant system. .

Vezujući agensi sintetizovani u ovom radu predstavljaju 1,3,5-trisupstituisane izocijanurate (supstituenti: 2-hidroksietil, 3-hidroksipropil, 2-hidroksipropil i 2,3-epoksipropil). Sve sintetske reakcije su izvedene koristeći modifikovane literaturne postupke. Svi dobijeni izocijanurati su okarakterisani temperaturama topljenja, FTIR, 1H NMR, i UV spektroskopskim podacima. FTIR je takođe korišćen za proučavanje interakcija između amonijum-perhlorata (AP), poli(butadiena) sa hidroksi i karboksi krajnim grupama (HTPB i CTPB), tetrametilentetranitramina (HMX) i jedinjenja sintetizovanih u ovom radu. Rezultati su pokazali da se 1,3,5-tri(2-hidroksietil)izocijanurat može koristiti kao univerzalni vezujući agens za AP/CTPB/HMX sistem kompozitnih goriva. .
