Inventia se refera la o instalatie de obtinere a polialcoxisiloxanilor alcatuita dintr-un vas de reactie în care se efectueaza reactia de esterificare, un reactor în care se efectueaza hidroliza si condensarea, un evaporator, în care se efectueaza evaporarea alcoolului, la presiune scazuta, un rezervor pentru alcoolul etilic recuperat, un filtru la care sunt transportati polialcoxisiloxanii ramasi în evaporator si un vas rezervor în care este stocat filtratul. Instalatia permite obtinerea unei game variate de polialcoxisiloxani, într-un timp scurt, în conditii eficiente.The invention relates to an installation for the production of polyalkoxysiloxanes consisting of a reaction vessel in which the esterification reaction is carried out, a reactor in which hydrolysis and condensation is carried out, an evaporator, in which the alcohol evaporation is carried out at a low pressure, a recovered ethyl alcohol reservoir, a filter to which the remaining polyalkoxysiloxanes are transferred to the evaporator and a reservoir vessel in which the filtrate is stored. The plant allows to obtain a wide range of polyalkoxysiloxanes, in a short time, under efficient conditions.
