Although the Spanish Royal Society of Chemistry (RSEQ) emerged in 1980, its history dates back to 1903, the year of the founding of the Spanish Society of Physics and Chemistry (SEFQ) and soon began publishing the journal Annals of the Spanish Society Physics and Chemistry. The number of members was 263 in the first year, professionals experimental sciences, primarily engaged in the field of chemistry. In the 1920s, after major development and internationalization, the company incorporated at the
IUPAC. In 1928, to mark the 25th anniversary of its founding, the company was honored by King Alfonso XIII with the name Royal Spanish Society of Physics and Chemistry. From this date forward, it created local branches (
Sevilla,
Barcelona,
Madrid,
Valencia) and hold biennial meetings of the Society. In 1934, the Royal Society organized the IX International Congress of Chemistry in Madrid, attended by 1,500 chemists in all countries. At that time, the Society already had about 1400 members. After the interruption of the Spanish Civil War and its disastrous consequences, the society began to reach new heights, especially from the 60s onward, as a result of the developing policies of the time. In the 70 territorial sections are consolidated specialized groups, such as
Organic Chemistry and Biochemistry (created in 1967), and
Adsorption (created in 1978). At the end of the decade it was decided to divide the society into two independent branches, the Royal Society of Chemistry (RSEQ) and Physics (RSEF). Successors of the work of the parent company held their biennial meeting in Burgos, 29 September to 3 October 1980. In the following years the focus groups were widespread within the RSEQ, and biennial meetings continued. The publication
Annals of Chemistry was divided into three series between 1980 and 1989: • Annals of Chemistry / Series A,
Physical Chemistry and Chemical Engineering, ( , CODEN AQSTDQ) • Annals of Chemistry / Series B, Inorganic and Analytical Chemistry, (, CODEN AQSAD3) • Annals of Chemistry / C Series, Organic Chemistry and Biochemistry (, CODEN AQSBD6) From 1990 to 1995, subseries A, B and C are joined to form again Annals of Chemistry, (, CODEN ANQUEX). Between 1996 and 1998 the magazine changed its name to Annals of Chemistry, International Edition, (, CODEN AQIEFZ) and published in English during this period. In 1998 it merged with other European publications, to edit together several magazines in English, but the tradition of publishing in Spanish with the founding in 1999 of continuing Annals of the Spanish Royal Society of Chemistry (Annals RSEQ), , quarterly. == Publications ==
