Solutions, formaldehyde Flash point

In methanol—formaldehyde—water solutions, increasing the concentration of either methanol or formaldehyde reduces the volatility of the other. Vapor-hquid-equihbrium data (8,27) for several methanolic formaldehyde solutions ate given in Table 2. The flash point varies with composition, decreasing from 83 to 60°C as the formaldehyde and methanol concentrations increase (17,18). 

Formaldehyde Solution — Fire Hazards Flash Point (deg. F) 182 CC (based on solution of 37 % formaldehyde and Methanol free), 122 CC (based on solution with 15 % Methanol) Flammable... 

FORMALDEHYDE (50-00-0) Forms explosive mixture with air [flash point gas 185°F/85°C flash point solution (methanol content lowers it) 122°-176 F/50°-80°C]. Aqueous solutions (37-55% by weight) are combustible and may explode above their flash points. Aqueous solutions slowly oxidize in air to formic acid. May polymerize unless properly inhibited (usually with methanol up to 15%) and stored at controlled temperature. 

TRIOXYMETHYLENE (30525-89-4) Combustible solid (flash point 158°F/70 C). Dust or powder forms explosive mixture with air. Aqueous solution produces formaldehyde.
