Fritz Raschig
Friedrich August Raschig (also called Fritz Raschig) (8 June 1863 – 4 February 1928) was a German chemist and politician. He was born in Brandenburg an der Havel. After he received his PhD in 1884 from the University of Berlin for his work with Robert Wilhelm Bunsen, he started working at the BASF company. In 1891 he opened his own chemical company in Ludwigshafen am Rhein (which still operates today as Raschig GmbH Company Website). He patented a number of chemical processes, particularly relating to phenols, one of which is now known as the Raschig phenol process, and nitrogen compounds—the [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Brandenburg An Der Havel
Brandenburg an der Havel () is a town in Brandenburg, Germany, which served as the capital of the Margraviate of Brandenburg until it was replaced by Berlin in 1417. With a population of 72,040 (as of 2020), it is located on the banks of the Havel, River Havel. The town of Brandenburg provided the name for the medieval Bishopric of Brandenburg, the Margraviate of Brandenburg and the current state of Brandenburg. Today, it is a small town compared to nearby Berlin but was the original nucleus of the former realms of Margraviate of Brandenburg, Brandenburg and Kingdom of Prussia, Prussia. History Middle Ages The castle of Brenna, which had been a fortress of the Slavic peoples, Slavic tribe Stodoranie, was conquered in 929 after the Battle of Lenzen by the Saxons, Saxon King Henry the Fowler. It was first mentioned as ''Brendanburg'' in 948. The name of the city is a combination of two words ''braniti'' – to protect/defend and ''bor'' – forest/wood. The town remained unde ...

Distillation
Distillation, or classical distillation, is the process of separation process, separating the components or substances from a liquid mixture by using selective boiling and condensation, usually inside an apparatus known as a still. Dry distillation is the heating of solid materials to produce gaseous products (which may condense into liquids or solids); this may involve chemical changes such as destructive distillation or Cracking (chemistry), cracking. Distillation may result in essentially complete separation (resulting in nearly pure components), or it may be a partial separation that increases the concentration of selected components; in either case, the process exploits differences in the relative volatility of the mixture's components. In Chemical industry, industrial applications, distillation is a unit operation of practically universal importance, but is a physical separation process, not a chemical reaction. An installation used for distillation, especially of distilled ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

German Protestants
The religion of Protestantism, a form of Christianity, was founded within Germany in the 16th-century Reformation. It was formed as a new direction from some Roman Catholic principles. It was led initially by Martin Luther and later by John Calvin. History The Protestant Reformation began with the publication of the ''Ninety-five Theses'' by Augustinian monk Martin Luther in 1517. The key element of this religious upheaval was a break from Roman Catholicism's emphasis on tradition, favouring a focus on the Bible. The lasting effects of Luther's Protestant movement within Germany was to question its existing power structures, imploring lay nobles for church reformation, critiquing the Roman mass, sacraments and seeking to reaffirm the importance of faith in good works. His subsequent excommunication from the Church ensured Germany had an ideological divide between Protestant sects and other Christian denominations. Another prominent reformer, Martin Bucer, introduced the r ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
People From The Province Of Brandenburg
A person ( : people) is a being that has certain capacities or attributes such as reason, morality, consciousness or self-consciousness, and being a part of a culturally established form of social relations such as kinship, ownership of property, or legal responsibility. The defining features of personhood and, consequently, what makes a person count as a person, differ widely among cultures and contexts. In addition to the question of personhood, of what makes a being count as a person to begin with, there are further questions about personal identity and self: both about what makes any particular person that particular person instead of another, and about what makes a person at one time the same person as they were or will be at another time despite any intervening changes. The plural form "people" is often used to refer to an entire nation or ethnic group (as in "a people"), and this was the original meaning of the word; it subsequently acquired its use as a plural form of per ...

Berichte Der Deutschen Chemischen Gesellschaft
''Chemische Berichte'' (usually abbreviated as ''Ber.'' or ''Chem. Ber.'') was a German-language scientific journal of all disciplines of chemistry founded in 1868. It was one of the oldest scientific journals in chemistry, until it merged with ''Recueil des Travaux Chimiques des Pays-Bas'' to form ''Chemische Berichte/Recueil'' in 1997. ''Chemische Berichte/Recueil'' was then merged with other European journals in 1998 to form ''European Journal of Inorganic Chemistry''. History Founded in 1868 as ''Berichte der Deutschen Chemischen Gesellschaft'' (, CODEN BDCGAS), it operated under this title until 1928 (Vol. 61). The journal was then split into: * ''Berichte der Deutschen Chemischen Gesellschaft, A: Vereins-Nachrichten'' (, CODEN BDCAAS), and * ''Berichte der Deutschen Chemischen Gesellschaft, B: Abhandlungen'' (, CODEN BDCBAD). Vol. 78 and 79 (1945–1946) were omitted and not published due to World War II. The journal was renamed ''Chemische Berichte'' (, CODEN CHBEAM) in 19 ...

Fractional Distillation
Fractional distillation is the separation of a mixture into its component parts, or fractions. Chemical compounds are separated by heating them to a temperature at which one or more fractions of the mixture will vaporize. It uses distillation to fractionate. Generally the component parts have boiling points that differ by less than 25 °C (45 °F) from each other under a pressure of one atmosphere. If the difference in boiling points is greater than 25 °C, a simple distillation is typically used. It is used to refine crude oil. Laboratory setup Fractional distillation in a laboratory makes use of common laboratory glassware and apparatuses, typically including a Bunsen burner, a round-bottomed flask and a condenser, as well as the single-purpose fractionating column. As an example, consider the distillation of a mixture of water and ethanol. Ethanol boils at while water boils at . So, by heating the mixture, the most volatile component (ethanol) will concen ...
