The glicerol and CO₂ are two organic compounds that nowadays revisten big importance since they can be raw materials alternatives to the oil for the synthesis of numerous derivative products, between which finds the carbonate of glicerol. This compound, has aroused big interest had to, mainly, to his properties, and to the big variety of uses and derivative applications.

In Tecnalia has llevar a thesis doctoral in that the one who have studied different indirect routes of production of carbonate of glicerol from intervals derived of glicerol (3-chlorine-1,2-propanodiol) and CO₂ (K₂CO₃ and KHCO₃ and DMC) easily sintetizables and much more reactive that the first.

The direct synthesis of carbonate of glicerol from glicerol and CO₂ would suppose a milestone in the chemical industry since it would involve to obtain a product of high value from two cheap sources and whose origin is distinct to the fossil. However, the up to now obtained performances are inferior to 10% like consequence of the low reactivity of the carbon dioxide.

Have developed technical processes and medioambientalmente efficient, prevailing in consequence the application of catalytic processes and exentos of dissolvent. After a comparative analysis of the routes studied (in which they consider technical appearances, economic and environingingmental), the most appropriate for the synthesis of carbonate of glicerol results the transesterificación of glicerol and DMC, although the route from 3-chlorine-1,2-propanodiol and CO₂, that uses TEA like agent of fixation-activation of CO₂, is also very promising.
