Cellulose-Based Absorbents

Examples of Cellulose-Based Absorbents include Slikwik庐 (ground corn cobs), saw dust, peat moss, and Sphagnum moss. The following categories of chemicals have been known to react (that is, are incompatibleSubstances that react together, if mixed.) with Cellulose-Based Absorbents:

Category: Acrylic Acids

• Reason for Concern:听Active sites on the absorbent may catalyzeTo act as a catalyst--that is, to speed up a chemical reaction between other substances without itself being chemically changed or consumed. polymerizationChemical reaction in which small molecules join to form larger molecules; polymerization reactions typically release heat, and can cause containers to overpressurize. of acrylic acid.
• Examples:听Acrylic acid; Methyl methacrylate; Methacrylic acid
• Reactive Groups:听Acrylates and Acrylic Acids

Category: 365bet娱乐 Susceptible to Air Oxidation

• Reason for Concern:听The exothermicA chemical reaction that generates heat. Opposite of endothermic, in which heat is taken in from the surroundings. air oxidationA chemical reaction in which oxygen bonds to an element or compound. By extension, a reaction in which one element or compound rises to a higher oxidation state while another drops to a lower oxidation state (the term is used in this sense even when no oxygen whatever is present). of these chemicals (while in contact with the absorbent) can cause a thermal runaway, especially when stored in a closed container.
• Examples:听Aldehydes, glycols, and other chemicals highly susceptible to air oxidation
• Reactive Groups:听Alcohols and Polyols;听Aldehydes

Category: Hydrazine, Hydrazine Derivatives, and Amines

• Reason for Concern:听These absorb strongly to Cellulose-Based Absorbents, releasing significant amounts of heat. The heat generated by this process can build up and cause the temperature to rise above the absorbed chemical's flash pointThe lowest temperature at which a liquid gives off enough vapor to be ignited at its surface.鈥攑ossibly resulting in a fire or explosionA chemical or physical process in which the rate at which energy is being generated exceeds its ability to escape to its surrounding environment. The hazards of an explosion can include a shock wave (especially near the point of explosion) and projectiles generated by the shock wave.. Hydrazine, many hydrazine derivatives, and many amines are highly flammableEasy to ignite and burns readily. and some are explosive.
• Examples:听Hydrazine; Trimethylamine; Diphenylamine
• Reactive Groups:听Amines, Aromatic; Amines, Phosphines, and Pyridines; Azo, Diazo, Azido, Hydrazine, and Azide Compounds

Category: Strong Caustics

• Reason for Concern:听These can hydrolyzeTo break down by means of reaction with water. the cellulosic structure, leading to an uncontrolled thermal runaway, which could result in a fire or explosion.
• Examples:听Sodium hydroxide; Potassium hydroxide
• Reactive Groups:听Bases, Strong

Category: Strong Oxidizers

• Reason for Concern:听These can oxidize the cellulosic structure of the absorbents, leading to an uncontrolled thermal runaway, which could result in a fire or explosion.
• Examples:听Nitric acid (can react with cellulose to produce explosive and flammable nitrocellulose); Concentrated peroxide-containing compounds; Concentrated persulfate compounds;听Concentrated sulfuric acid
• Reactive Groups:听Acids, Strong Oxidizing; Nitrate and Nitrite Compounds, Inorganic; Nitro, Nitroso, Nitrate, and Nitrite Compounds, Organic; Oxidizing Agents, Strong; Peroxides, Organic

Category: Water-Reactive 365bet娱乐

• Reason for Concern:听Cellulose-Based Absorbents often contain moisture, which could pose a hazard if they are used to clean up water-reactiveCan react vigorously when mixed with water or steam or when spilled into water; the reaction may generate hazardous gas or overpressurize a container. chemicals. Many water-reactive chemicals release toxicPoisonous; can injure or kill people or other organisms. or corrosiveLiquid or solid that can destroy human skin or lung tissue or corrode metals. gases and generate heat when they come into contact with even small amounts of water.
• Examples:听Methyl isocyanate; Acetyl chloride; Acetic anhydride; Phenyltrichlorosilane
• Reactive Groups:听Acid Halides, Sulfonyl Halides, and Chloroformates; Anhydrides; Chlorosilanes; Halogenating Agents; Isocyanates and Isothiocyanates; Thiocarbamate Esters and Salts/Dithiocarbamate Esters and Salts
