In 1843, Marx became co-editor of a new, radical leftist Parisian newspaper, the Deutsch-Französische Jahrbücher ( German-French Annals ), then being set up by the German socialist Arnold Ruge to bring together German and French radicals  and thus Marx and his wife moved to Paris in October 1843. Initially living with Ruge and his wife communally at 23 Rue Vaneau , they found the living conditions difficult, so moved out following the birth of their daughter Jenny in 1844.  Although intended to attract writers from both France and the German states, the Jahrbücher was dominated by the latter and the only non-German writer was the exiled Russian anarchist collectivist Mikhail Bakunin .  Marx contributed two essays to the paper, " Introduction to a Contribution to the Critique of Hegel's Philosophy of Right "  and " On the Jewish Question ",  the latter introducing his belief that the proletariat were a revolutionary force and marking his embrace of communism.  Only one issue was published, but it was relatively successful, largely owing to the inclusion of Heinrich Heine 's satirical odes on King Ludwig of Bavaria , leading the German states to ban it and seize imported copies (Ruge nevertheless refused to fund the publication of further issues and his friendship with Marx broke down).  After the paper's collapse, Marx began writing for the only uncensored German-language radical newspaper left, Vorwärts! ( Forward! ). Based in Paris, the paper was connected to the League of the Just , a utopian socialist secret society of workers and artisans. Marx attended some of their meetings, but did not join.  In Vorwärts! , Marx refined his views on socialism based upon Hegelian and Feuerbachian ideas of dialectical materialism, at the same time criticising liberals and other socialists operating in Europe. 
Because wood-tar creosote is used for its guaiacol and creosol content, it is generally derived from beechwood rather than other woods, since it distills with a higher proportion of those chemicals to other phenolics. The creosote can be obtained by distilling the wood tar and treating the fraction heavier than water with a sodium hydroxide solution. The alkaline solution is then separated from the insoluble oily layer, boiled in contact with air to reduce impurities, and decomposed by diluted sulphuric acid. This produces a crude creosote, which is purified by re-solution in alkali and re-precipitation with acid and then redistilled with the fraction passing over between 200° and 225° constituting the purified creosote.
