93% for BDM25, 87% for BDM65 and 27% for soybean
oil that were interpreted as volatilization. The TG curve for
(2,2-dimethyl-1,3-dioxolan-4-yl)-methyl palmitate (PDM)
was very close to the BDM65 curve.
These results showed that dioxolanyl-methyl esters
promoted an increase in the final distillation temperature of
the products. However, considering the TG analysis and the
ASTM distillation curve for BDM25, it can be inferred that
as much as 25% of dioxolanyl esters could be added to
biodiesel methyl esters without interfering with its vola-
tilization behaviour. Most interesting, this technique
allowed a prediction of the distillation behaviour of the
product BDM65 without being necessary to perform a
distillation according to ASTM.

Conclusions
The thermal properties measured for the BDM products,
the (2,2-dimethyl-1,3-dioxolan-4-yl)-methyl esters of fatty
acids, presented values close to those obtained for a soy-
bean methyl biodiesel. Thus the substitution of methyl
alcohol by a glycerol derivative in the structure of fatty
esters resulted in a product with good potential to be used
as a biofuel according to the measured thermal properties.
The conversion of such a glycerol derivative into a product
