Hazard Predictions

• Flammable: Reaction products may be flammable
• Generates gas: Reaction liberates gaseous products and may cause pressurization
• Generates heat: Exothermic reaction at ambient temperatures (releases heat)
• Unstable when heated: Reaction products may be unstable above ambient temperatures
• Intense or explosive reaction: Reaction may be particularly intense, violent, or explosive

The hydroxyl proton of an alcohol or hemiacetal is easily extracted by strong reducing agents to yield flammable hydrogen gas. In many cases ignition occurs, and sometimes explosions also occur. (Rich, G. A., 1993, Dangerous Chemical Reactions, Gulf Publishing Co., Houston, TX, p. 256)

Inorganic reducing agents may reduce alcohols and alcohol-like hemiacetals to hydrocarbons (Predicted). Saturated hydrocarbons with fewer than five carbons are flammable gases.

However, we expect the weak reducing agents in this group to be less reactive in this way than stronger reducing agents, resulting in a less hazardous situation than if strong reducing agents were involved. We urge chemists to do small scale testing before proceeding.
