How Do Specialty Chemicals Differ From Commodity Chemicals?

Specialty chemicals differ from commodity chemicals. While commodities have dozens of different applications for each chemical, specialty chemicals have only one or two uses. Commodity chemicals make up most of the manufacturing volume (in other words, by weight) in the global marketplace, and specialty chemicals make up most of the diversity, number of different chemicals, in commerce at any given time.

Commodity chemicals are generally produced in continuous processes, 24 hours a day, 7 days a week. On the other hand, specialty chemicals, due to their complex chemistry and narrowly focused applications, are mostly produced batch-by-batch in a reaction vessel. Since continuous processes incorporate continuous feeds and yields, the production volume is usually much greater, per chemical, than for batch processes.

However, the main difference is that a batch process is not necessarily automated, and the chemical reaction which yields the desired product has a discrete beginning and ending for each batch.
