HERRERA HUIZA, Carolina  and  AMURRIO DERPIC, David. Cellulose acetate from Viguiera tucumanensis. RevActaNova. [online]. 2021, vol.10, n.1, pp.96-105. ISSN 1683-0789.

Cellulose acetate was synthesized from cellulose extracted from an endemic species, V. Tucumanensis, Reagents required for the acetalization like SOCl2, SO3 were synthesized starling from common over the counter substances. The resulting product was formulated with different proportions of glycerin until a flexible product was obtained and characterized as having 1.05 ± 0.1 g/cm3 density, 6.19 ± 0.24% humidity, 8.26 ± 0.2% water absorption, 2.25% elongation (under 0.147 N at 20°C for 6 days, equivalent to a 0.0075 kg/cm2 elasticity modulus), and 8.71% weight loss biodegradability under composting conditions.

Keywords : Cellulose acetate; thionyl chloride synthesis; Viguiera tucumanensis.
