Glycerine Facts

If hydride is in the form of granules and glycerine is in the pure state, the alcohol combusts. The fact that its thickness limits the heat dissipation makes it responsible for this behaviour. When glycerine is diluted with tetrahydrofuran, for instance, there is no ignition. 

Q. Dr. Ambros, is it not a fact that as far back as early 1935, when the vermittlungstelle Wehrmacht was first conceived, you took part in discussions between Farben and Army Ordnance as to the urgent needs for synthetic glycerine ... 

Very recently Ropuszynski [33] has proved that nitrating glycerine at an elevated temperature exerts a propitious influence upon the stability of the product This is due to the fact that nitroglycerine obtained at a higher temperature before being stabilized by the usual methods i.e. is washed by means of water and of sodium carbonate solution, contains less residual acid. 

Glycol can be nitrated in the same vessels as glycerin - in batches or continuously. The same applies to its separation and washing, which are in fact easier since nitroglycol is less viscous. 

We determined that vicinal dihydroxy organic reagents stabilize the soluble forms of silica. The stability of monosilicic acid solution is determined by the structure of the stabilizer ethylene glycol and humic acids do not stabilize soluble forms of silica enough, but glycerin and catechol stabilize the silica solution when they are added at 5 - 7% to the solution. This fact is connected with the formation of hydrogen bonds and stable penta- and hexacoordinated compounds, preventing the processes of polycondensation of silica in solution. 

Mr. Wislicenus has, in fact, recently announced that he has found an active acid in meat. This acid does not have, as has been believed, the constitution of the ethylene lactic acid but it is according to this author a physical isomer of the ordinary lactic acid. Indeed one cannot see that the ethylene lactic acid can be active, for the carbons of the radical are each one combined with two atoms of hydrogen, as the formula shows CH2 OH CH2 GOOH. We see also that the propylene glycol and the iodopropionic acid which are derived from the active lactic acid will preserve the rotatory power, but it will not be the same with the glycerine which one can derive from it, for in that case the central carbon atom is united with the two equal radicals CH2 OH,...

Due to the fact that large amounts of glycerin are. imported into this country annually the development of glycerin production should be an inviting enterprise.
