Provided are a water-soluble triarylphosphine for a palladium catalyst, which has high selectivity in a telomerization reaction and can be recovered with efficiency, an ammonium salt thereof, and a method for efficiently producing the same. Specifically, provided are bis(6-methyl-3-sulphophenyl)phenylphosphine; a bis(6-methyl-3-sulphonatopheyl)phenylphosphine diammonium salt obtained by reacting the phosphine with a tertiary amine having a total of 3 to 27 carbon atoms in groups bonded to one nitrogen atom; and a method for producing the same.

The present disclosure provides a method for stably supplying a highly pure n-butylamine gas having a constant composition. The present disclosure is a composition supply method including: a filling step of filling a container with a composition containing n-butylamine in an amount of 99.5% by volume or more and isobutylamine in an amount of 0.001% by volume or more and 0.5% by volume or less; a warming step of warming the container filled with the composition to 50 C. or higher; and a gas supply step of supplying a gas containing n-butylamine and isobutylamine from the warmed container to a predetermined device.

The present application provides solvent-free methods for decarboxylation of amino acids via imine formation with a ketone, enone, enal, aldehyde co-reagent or combination thereof, under heated conditions, with optional recovery of the co-reagent and/or co-reagent byproduct.
