Autocatalytic – Definition & Meaning

Autocatalytic is a term that is often used in the fields of chemistry and biology. It is a complex term that can be difficult to understand, but it is important for those who work in these fields to have a solid understanding of what it means. In this article, we will explore the definition and meaning of autocatalytic, as well as its origin, associations, synonyms, antonyms, and example sentences.


Autocatalytic is defined as a reaction or process that is self-sustaining, meaning that it produces its own catalyst. In other words, the reaction or process is able to continue without the need for external input. Autocatalytic reactions are often used in chemical synthesis and organic chemistry.


The term autocatalytic comes from the Greek words “auto” meaning self and “catalysis” meaning to speed up a chemical reaction. The term was first used in the early 20th century by chemists who were studying the behavior of certain chemical reactions.

Meaning in different dictionaries

Autocatalytic is a technical term that is not commonly found in general dictionaries. However, it can be found in scientific and technical dictionaries, where it is defined as a self-sustaining reaction or process.


Autocatalytic reactions are often associated with organic chemistry and chemical synthesis. They are also used in the study of biological systems, such as enzymes and metabolic pathways.


Some synonyms for autocatalytic include self-catalyzing, self-generating, and self-propagating.


There are no direct antonyms for autocatalytic, as it is a technical term that describes a specific type of reaction or process.

The same root words

The root words of autocatalytic are “auto” meaning self and “catalysis” meaning to speed up a chemical reaction. Other words that use these root words include autotrophic (self-nourishing) and catalytic (related to catalysis).

Example Sentences

  1. The autocatalytic reaction produced its own catalyst, allowing it to continue without external input.
