Formaldehyde dimethylacetal

Methylene chloride is probably the most generally used solvent for decaffeination processes, but others, some of which are already found in small amounts in coffee beans, are coming into use. For example, ethyl acetate,8 formaldehyde-dimethylacetal, ethanol, methanol, acetone,9 propane,10 benzyl alcohol,11 carbon dioxide,12 and supercritical carbon dioxide with an acid13 are used. Generally the pressure and temperature of the system are adjusted to keep the solvent in the liquid state. Coffee oil itself is even described for this use in one patent.14... [Pg.93]

Trimethylorthoformate 17 is a highly activated Cl building block and a formic acid equivalent which is commonly applied in organic condensation reactions. 17 can be produced on an industrial scale by two major routes. The first starts with chloroform and sodium methanolate, but produces 3 equiv. of sodium chloride as waste. The second route is based on the acidic methanolysis of cyanhydric acid, which also produces stoichiometric amounts of ammonium chloride. Despite the reduced salt waste, the use and handling of cyanhydric acid mean high safety costs. Therefore, anodic methoxylation of formaldehyde dimethylacetal (16) to... [Pg.12]

For example, the anodic methoxylation of formaldehyde dimethylacetal (5, FADMA) to trimethyl orthoformate (6, TMOF) proceeds well on BDD electrodes in undivided cells (Fig. 5.5) (Fardel et al. 2006). TMOF is obtained in 75% selectivity at 27% FADMA conversion at a charge consumption of 0.4 F mol-1 FADMA, according to a current efficiency of 41%. This reaction is not possible using graphite electrodes. [Pg.129]

FORMALDEHYDE DIMETHYLACETAL (109-87-5) Forms explosive mixture with air (flash point —26°F/—32°C oc). Forms unstable peroxides in storage. Violent reaction with strong oxidizers. Incompatible with acids. Attacks some plastics, rubber, and coatings. Flow or agitation of substance may generate electrostatic charges due to low conductivity. [Pg.575]

Although phenols are known to react very rapidly under Blanc conditions and often result in polymeric materials, when substituted with an electron-withdrawing substituent they become suitable substrates for this reaction. As shown below, p-nitrophenol (16) is chloromethylated using the dimethylacetal of formaldehyde giving 17 in relatively high yield. °... [Pg.595]
