Description

Przedmiotem niniejszego wynalazku jest sposób otrzymywania chlorku metanu, polegajacy na tern, ze mieszanine chloru i metanu, w której metan zawarty jest w nadmiarze, poddaje sie odpowiednim wa¬ runkom reakcji.Dalsze poszukiwania wykazaly, ze przez odpowiedni dobór warunków pracy daje sie wytworzyc latwo rozdzielajaca sie mieszanine chórku metanu i chlorku metylenu. Ten wynik osiaga sie przez to, ze mieszanine, która na 1 objetosc chloru nie zawiera istotnie mniej niz 3 i nie wiecej niz 8 objetosci metanu, a zazwyczaj miesza¬ nine 1 objetosci na 4 — 6 objetosci metanu poddaje sie dzialaniu temperatury okolo 4(K)o _ 600q c.Gdy np. ogrzeje sie mieszanine 1 obje¬ tosci chloru z 4 — 6 objetosciami metanu do temperatur okolo 400° — 600° C, to raz rozpoczeta akcja przebiega bez doprowa¬ dzania ciepla od zewnatrz, skoro straty cie¬ pla zostana usuniete zapomoca odpowied¬ niej izolacji. Wypelnianie przestrzeni reak¬ cji odpowiedniemi porowatemi cialami przy¬ spieszaj acemi reakcje okazalo sie korzy- stnem — jednakowoz nie koniecznem. Pod wplywem wyzej przytoczonych warunków mozliwem jest np. na 100 czesci chlorku me¬ tanu wytworzyc 85 czesci chlorku metylenu, unikajac powstawania innych cial. Wytwa¬ rzanie wprost wyzszych produktów chlo¬ rowania metanu z duza wydajnoscia ma nadzwyczajne praktyczne znaczenie. Z ba¬ dan Tolloczki (Chemisches Centralblatt 1913 Tom 2 str. 99) musiano jednakprzyjsc do przekonania, ze wytwarzanie wprost jednolitych chlorków metanu z metanu nie da sie zastosowac w przemy¬ sle, albowiem Tolloczko otrzymal, np. przy chlorowaniu z nadmiarem gazów nafto¬ wych, 0,35 czesci gazowych i 0,79 czesci oleistych produktów chlorowania. Jak wskazuje zestawienie otrzymanych przez Tolloczke produktów koncowych, zuzyto znaczna ilosc chloru do utworzenia wyz¬ szych produktów chlorowania i kondensa¬ cji, które otrzymano w postaci malowarto- sciowych, tylko z trudem dajacych sie roz¬ lozyc na skladniki, mieszanin substancyj.Tern niemniej otrzymuje sie wedlug ni¬ niejszego sposobu wprost chlorek metyle¬ nu z dobrym wynikiem obok chlorku me¬ tanu- PL PLThe subject of the present invention is a method for the preparation of methane chloride, consisting in the fact that a mixture of chlorine and methane, in which methane is present in excess, is subjected to appropriate reaction conditions. a mixture of methane chloride and methylene chloride. This result is achieved by the fact that a mixture which for 1 volume of chlorine does not contain significantly less than 3 and not more than 8 volumes of methane, and usually a mixture of nine 1 volume per 4 - 6 volumes of methane, is subjected to a temperature of about 4 (K ) about 600 ° C. If, for example, a mixture of 1 volume of chlorine with 4 - 6 volumes of methane is heated to a temperature of about 400 ° - 600 ° C, once started the action takes place without the addition of heat from the outside, since heat is lost the beach will be removed with proper isolation. Filling the reaction space with suitable porous bodies to accelerate the reaction has proved to be an advantage - but not necessary. Under the above-mentioned conditions it is possible, for example, for 100 parts of methylene chloride to produce 85 parts of methylene chloride, avoiding the formation of other bodies. It is of extreme practical importance to produce directly higher methane chlorination products in high yield. From the Tolloczko study (Chemisches Centralblatt 1913 Vol. 2 p. 99), however, it had to be convinced that the production of directly homogenous methane chlorides from methane could not be used in industry, because Tolloczko was obtained, for example, during chlorination with excess gases of naphtha. products, 0.35 parts of gaseous and 0.79 parts of oily products of chlorination. As the summary of the end products obtained by Tolloczka shows, a considerable amount of chlorine was used to form the higher products of chlorination and condensation, which were obtained in the form of paints, only difficult to break down into constituents, mixtures of substances. according to the present method, methylene chloride is directly present with good results in addition to methane chloride - PL PL
