Reactive Group Datasheet

Sulfides, Organic

What are reactive groups?

Reactive groups are categories of chemicals that typically react in similar ways because they are similar in their chemical structure. Each substance with a chemical datasheet has been assigned to one or more reactive groups, and CAMEO Chemicals uses the reactive group assignments to make its reactivity predictions. More Info...

If you can't find a chemical in the database--but you know what reactive group it belongs in--you can add the reactive group to MyChemicals instead in order to see the reactivity predictions.

There are 187 chemical datasheets assigned to this reactive group.

Description

Flammability

The low-molecular-weight gaseous and liquid sulfides (such as methyl mercaptan or ethyl mercaptan) are extremely flammable, but flammability diminishes with increasing molecular weight. The products of combustion include sulfur dioxide.

Reactivity

Materials in this group are incompatible with acids, diazo and azo compounds, halocarbons, isocyanates, aldehydes, alkali metals, nitrides, hydrides, and other strong reducing agents. Reactions with these materials generate heat and in many cases hydrogen gas. Many of these compounds may liberate hydrogen sulfide upon decomposition or reaction with an acid.

Toxicity

Most organic sulfides are toxic by inhalation. In general, they are stenches. Thus methyl mercaptan is added to natural gas (which is odorless) to assist in the detection of leaks.

Other Characteristics

Compounds in this group are characterized by an organic group attached to a sulfur atom R-SH; disulfides have the formula R-S-S-R. Their reactions resemble those of alcohols. These chemicals are used in industrial synthesis of chemicals, and are important as catalysts, as additives in petroleum and natural gas, and as pesticides.

Examples

Amyl mercaptan, butyl mercaptan, diamyl sulfide, dimethyl sulfide, ethyl mercaptan, propyl mercaptan, methyl mercaptan.
