With the aim of offering the specific terminology on organic chemistry, inorganic chemistry, physical chemistry and analytical chemistry to chemistry students and teachers, we present the Diccionari de química ('Dictionary of chemistry'), that gathers more than 2,000 Catalan terms with definition and equivalents in Spanish and English, including, where appropriate, the corresponding symbol or formula. In addition, many of the entries contain extensive notes with detailed information and images that graphically illustrate some aspect of the term defined.

It is complemented by an interactive infographic of the periodic table of the elements and annexes, in Catalan, about nomenclature and formulation.

The work is the result of the collaboration between terminologists and specialists on this field.

This online dictionary gathers a selection of terms from a wider terminological project on chemistry terms, currently in preparation. TERMCAT publishes this partial data online to facilitate public consultation. Its intention is to enlarge the selection of terms with words belonging to the other areas of knowledge in the future.

Clicking on "Consulta de termes" (‘Term search’), terms can be looked up in three ways: using the alphabetical indexes (there is a different index for each language), using the thematic access or making simple or advanced searches in the upper space "Text de la consulta" (‘Text search’) in any of the dictionary languages.
