  • Method for the recovery of compounds deriving from the synthesis of poly aryl ether ketone polymers
    Patent number: 10731001
    Abstract: A method for treating a shear-thinning residue composition deriving from the synthesis of an aryl ether ketone, the residue composition including a liquid fraction and solid residues, the method including the steps of: passing said shear-thinning residue composition through a shear-generating evaporating device, between a rotating part and a stationary part; and recovering a condensed liquid fraction and separately recover concentrated solid residues.
    Type: Grant

  • Process for recovering acrolein or propionaldehyde from dilute aqueous streams
    Patent number: 6515187
    Abstract: A method of purifying acrolein or propionaldehyde with a single column distillation system is provided, where the distillation system has a side-draw take-off outlet for recovering purified acrolein or propionaldehyde located between the crude product feed point and the light-boiling impurities distillation site.

  • Process for the preparation of alkane sulfonic acid and alkane sulfonyl chloride
    Patent number: 6066760
    Abstract: A process is disclosed for the efficient production of high purity alkane sulfonic acid and/or alkane sulfonyl chloride product wherein a compound of the formula RSX, where X is hydrogen or --SR.sup.1 and R and R.sup.1 are alkyl radicals is continuously reacted with chlorine in aqueous hydrochloric acid to produce a turbulent evolution of hydrochloride gas, passing the reactants through stationary mixing elements to promote plug-flow, and separately withdrawing a product. Apparatus for this process is also disclosed.
