Abstract

Synthesis and characterization of trimethoxy boroxine

Abstract

Trimethoxy boroxine is used in fire
extinguishing tubes because of its smoke suppressant properties and it is also
used as an auxiliary catalyst in olefin polymerization, in lithium ion cells as
an electrolyte additive, in welding and soldering works, in protective coating
production and in hardening of epoxide resins. It has become a desirable
material because of its superior properties and it has gained importance how to
synthesize it cheaper and easier. In this study,  trimethoxy boroxine was synthesized from the
reactions of boric acid and trimethyl borate. In the first step, boric acid
reacted with methanol in order to obtain trimethyl borate as a precursor. The
best reaction yield was obtain by using 1:2 ratio of boric acid and trimethyl
borate in cyclohexane. Trimethoxy boroxine was synthesized from boric acid and
trimethyl borate in azeotropic distillation set-up containing Dean-Stark
apparatus. It was characterized by H-NMR and FT-IR.
