Magnesium methyl carbonate, methoxy

Figure 24 Comparison of isothermal chemiluminescence intensity for pullulan (1) and pullulan impregnated by methoxy magnesium methyl carbonate (2) from a 5% solution in methanol initial molar mass of pullulan 404 kg/mol, oxygen atmosphere, temperature 190°C.

The most successful nonaqueous deacidification treatment is the Wei T o process which uses solutions of methoxy magnesium methyl carbonate in alcohol and Freon as the starting materials (33). The spray deacidification of the solution on books is now in use at the... 

The methoxy magnesium methyl carbonate (H COMgOCOOCH,) after being deposited in the fibers by the solvents, reacts witn water from the air to form a mixture of magnesium carbonate (MgCO ), magnesium hydroxide [Mg(OH )], and magnesium oxide (MgO) ... 

Wei T o Process. Wei T o process is the only mass deacidification process currently available commercially. The "liquid gas" deacidification solution of this process consists of methoxy magnesium methyl carbonate dissolved in a mixture of Freon and methyl alcohol. The process has been proven by six years of production operation at the National Library and Public Archives of Canada. It utilizes a less complex system than the DEZ process to achieve deacidification. National Library and Public Archives of Canada are satisfied with the deacidification results.

Carboxylation of activated CH groups with MMMC (methoxy magnesium methyl carbonate) 1 (Szarvasy) and addition of the resulting activated groups to C=N bonds (Schopf) (see 1st edition). 

In the presence of methoxy magnesium methyl carbonate, the chemiluminescence emission in pullulan and cellulose increased significantly. It may be attributed to the decomposition of dioxetanes, with higher quantum yield of emission, which were formed from peroxidation of terminal semiacetal groups in the presence of MgO.
