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.
