A new synthesis of Phenylacetones and synthesis of 2-5-dimethoxy -4-methylbenzaldehyde both have been requested at the hive for a while. These articles have an english abstract but the rest is in chinese . Need some help in translation of articles.........java
here are the articles......
http://home.ripway.com/2004-11/211899/anewsyntheticMethodofPhenylacetones-synthesisof2-5-dimethoxy-4-methylbenzaldehyde.pdf
Note ripway the host only allows 3MB of downloading /24hrs so if not able to download just wait 24hrs then you can do it...sorry for the inconvenience......java |

Here are additional articles needing translation from Japanese to English, as they deal with the subject of benzaldehyde conversion with amino acid to ephedrine and nor ephedrine.......java
-------------------------------------------------------------------------------------------------
These are articles in Japanese that deal with akabori synthesis of ephedrine and norephedrine.......because they're bundled one is in english.....

ok, i started a translation of the scanned sites on cocaine manufacturing, here is what
i have done so far. please post any comment on incomprehensible parts. sorry
for my worse english, but you might help me to improve the translation.
so this is a translation of the first site and the beginning of the second. i'll continue
within the next days. if i have finished and the text will be considered as "good enogh" i also could make a pdf from it

Technical Manufacturing of Cocaine
Production of cocaine base:
The important routings are: extraction, separation and purification of the "raw" bases.
Because of the high volumes of coca leaves which perish on transports and
decreasing alkaloid assay, the extraction almost is done locally / on-site.
Extraction of cocaine base from leaves of american origigin is made as following:
The grinded leaves are moisted with sodium carbonate h2o. Then an extraction is
done using common extracting devices, using ether (diethyl) or benzene.
If ether was used, then some of the ether will be distilled off, then the solution gets
shaken with diluted hcl*h2o (recrystalising). Using solvents with higher boiling
points the complete solution gets shaken with diluted hcl*h2o. The alkaloids will
dilute aqueous as hydrochloride salts. Then ammonia or sodium carbonate are
used to precipitate and the the base(s) will be filtrated off. These (bases) now will
be dried and worked up as described further...
Within the next steps of cocaine manufacturing pure cocaine from the raw cocaine
the cocaine will be separated from the other alkaloids ecgonine, cinnamyl-, isatropyl-
cocaine and others...
These alkaloids will be degraded (derived) to ecgonine, from which synthetic cocaine
can be made.
Analyzing of the content.
To determine the content in raw cocaine 50 g will be solved in 500 cm² of 3%
aquaeous sulphuric acid, using ice the solution is cooled down to 3-4° C.
Now a (cold) saturated solution of MnO4 is added dropwise until the red colour
stops disappearing. Within this procedure the temperature must not rise 4° C.
The solution ** ... is made basic with ammonia
##here i'm not quite sure about the translation, as the text is rather oldfashioned
german. i guess he means the solution is made partially basic with ammonia
cause then he says:
and then the cocain is completely precipitated with "potash" (which is potassium
carbonate?)
After leaving for a while the cocaine is vacuum filtrated off, then let dry on ceramic
plates in the dyer (dry box) at a temperature of 30° - 40° C.
After the drying the cocaine is filled in a bottle (glass) and shaken with ether. The
ether is filtrated off the sludge and distilled off in a weighed flask. The residue
should be shiny, a content of 70 - 90%.

edited again:
i finally found the german->english dictionary in the ebooks forum. that makes it easier to translate, but won't change my mistakes on grammar  |

The fabrication of the pure cocain follows the way of an analysis :
In a 70 l vessel 7 kg of the raw cocain is dissolved in diluted H2so4 ( 15 kg h2o and 1,2 kg 99% H2so4)
this solution is kept at a temprature of 4 ° during the whole process by addition of junks of ice with
about fist sice , the ice i directly dropped into the cocain solution .
Over the vessel a container is put wich is filled with a 10 % kaliumpermanganate solution .
Out of this container the KMnO4 is added with a thin spurt to the cocain solution , under good stirring ,
during this addition it is important to keep the tmp . low so it doesnt exeed 4 ° . ( @ higher tmp the cocain is easily oxidated )
the addition of Kmno4 is stopped when the foam in the vessel got a bright red colour that doesnt dissapear within
0.5 h . Then it is basified with ammonia and precipitated with K2Co3 ( potasses) untill the filtered probe
by addition of ammonia and K2Co3 get no more turbidly . With fast precipitation the cocain falls out as a smudgy
mass , but gets fast hard by injection of a cristall or kneadin .the cocain is now split up in diffrent ceramic nutsches
and rewashed with water afterwards dried at 60C on ceramic . The dried , with manganeseoxides decolouriced product
is put in thight neck 12l flasks wich filled to about 1/4 of their capacity . then those flasks are filled to a half with ether
wich is filtered into a dest. roundbottom flask . the residue in the flask is to be extracted multiple times with ether .
The united and filtered ether solutions are destilled , when the residue has goten a oliveoil like consistency ,
the destillation is stopped and puts the dest .roundbottom residue into a wide neck jar with about 6 l capacity
The cristallisation starts outright and is finished after 12 h. the cleaned cocain precapitated out at the walls of the flask
as hard crusts , wich are removed carefully . To do so iron wires ( D :5 mm) flattend at one and and with a knob are used .
the cristalls are now minced covered 2 times with ether and nutsched . thereupon the xtals are air dried .
the mother ether solution are further boiled off and brought to cristallisation . By doing so more base is gathered wich is oxidated by the
process already described . The cocain gained from ether is clean enough for every sort of salt- making
the no futher end solution are thick and brown , they are diluted with same amount of ether and shaken with 5 parts
petrolether . the petrolether takes up benzoylcocain , while the isatropylcocain smudgy remains .
if something hard falls out , so is it to be washed with ether again , and treated with petrolether .
when the petrolehter solutions are exposed to hcl containing alcohol until no more salt falls out then the motherliquour
contains no more cocain . the remaining smudges are destroyed , to gain ecgonin ( see above ).
cocain hydrochloricum comes to stores in form of little flakes and water containing cristalls .
The on mentioned fitst is prepared by dissolving the cocain in aceton and
adding the needed amount of Hcl:
0.5 kg cocain is taken up in 2 l of aceton , the solution filtered in a wide neck flask and stirred with a glass rod
the calculated amount of 38% Hcl aq i added . shortly of the addidtion the hcl nice flakes of the hydrocloride
fall out , these are nutsched off after 12 h , rewashed 2 times with aceton , and dried at 50C .

ahh well its done took me half an h im pretty sure there are plenty of mistakes ^^
when u find mistakes , keep em |
