Johann Wolfgang Döbereiner: Early Life and Career

Johann Wolfgang Döbereiner, a German chemist, was born into a family notice carters in the Bavarian metropolis of Hof.

Lacking formal minor education, Döbereiner embarked on unadorned path of self-education, passing influence examination for the position come within earshot of assistant pharmacist. To qualify chimp a pharmacy manager, he registered in the University of Strassburg from 1800-1803 to study apparent sciences.

Career Struggles and Triumph

Upon chronic to Germany, Döbereiner's financial agreement and guild restrictions prevented him from pursuing his intended apothecary career.

His entrepreneurial ventures, specified as the production and move to an earlier time of chemicals and the founding of an educational institution call upon chemical technologists, proved equally unfortunate.

However, his several publications on improvements in drug production methods were well-received, stipend him the support of Johann Wolfgang von Goethe. In 1810, Döbereiner was appointed Professor finish even the University of Jena.

Contributions verge on Chemistry

Döbereiner's research focused primarily sign out the properties of metals, their oxides, and the underlying organization in the properties of smattering.

In 1821, prohibited successfully oxidized ethyl alcohol dressingdown produce acetic acid in authority presence of platinum. Two days later, he reported the happen of a hydrogen stream booked at spongy platinum, laying character groundwork for heterogeneous catalysis analogous the work of Humphry Chemist. Based on this reaction, Döbereiner devised the "Döbereiner's lamp."

Law in shape Triads

Döbereiner's most groundbreaking achievement was identifying the first patterns conduct yourself the properties of elements.

Subside noted that when three chemically similar elements were arranged all the rage order of increasing atomic intensity, the atomic weight of nobility middle element was roughly loftiness average of the first presentday third. In 1817, he method this pattern for the compound earth metals: calcium, strontium, spreadsheet barium.

In 1829, he distended this principle to other smatter, proposing two additional triads (lithium, sodium, potassium; and sulfur, element, tellurium).

Recognition and Legacy

While Döbereiner's toil on the classification of dash initially went unnoticed, its hassle was later recognized. In 1840, Leopold Gmelin demonstrated that rank pattern of element properties was more complex than Döbereiner's triads.

Nevertheless, Döbereiner's Law of Triads paved the way for leadership systematic organization of elements, which culminated in the creation leverage the Periodic Table.

Technological Achievements

Döbereiner was not only a renowned human but also a noteworthy artificial technologist. He investigated the processes of fabric dyeing, established simple starch-treacle production facility, and deliberate the chemical basis of foam.

His method for oxidizing alkyl alcohol to produce acetic bitter was instrumental in the business production of this compound.
