Looking for cheapest method for methylpropiophenone (large scale)

[woohoo]

How china labs making it so cheap?
Is it made in tube furnace (like p2p from phenylacetic and acetic acids)?
Friedel Crafts is very expensive for large batches.

 

[woohoo]

Any info?

 

[HIGGS BOSSON]

Chinese factories have great technological capabilities that allow for cheap syntheses. This cannot be repeated at home.

 

[woohoo]

Which route they're using?

Hi. As @HIGGS BOSSON said, they have high-tech equipment, access to precursores. Large loads have less costs and this reduces the cost of products. Also, they, probably, have own know-how to make it cheap. It is sort kind of manufacturer secret.
