Foto de stock - Jul. 29, 1952 - German Chemist invents synthetic glycerine: Our Francfort correspondent reports: Mr. Herbert Kurth, a resident of Oberursel, District Francfort/Main, Germany, had already gained much reputation by the invention of synthetic resinoids and synthetic sugar, a substance he called 'Zuckerit'. He worked sixteen years to develop the theory and manufacture of synthetic glycerine. This substance called 'Kurozin', is nothing but a condensation of formaldehyde with additional substances which have the very some chemical and physical characteristics as glycerine. Nitro-Kurozih, also called 'Kurealomil' is even more dangerous than Nitro-glycerine. So far Germany had to import annually 6,000 tons of glycerine. The inventor hopes that his works will save the indigenous economy thousands of Deutschmarks otherwise spent to import this important raw material.
