  • Publication number: 20240102060
    Abstract: The present invention relates to an alcohol acyl transferase which is capable of esterifying a tertiary monoterpene alcohol such that at least 30% by mass of said tertiary monoterpene alcohol is esterified, preferably within 36 h, 24 h, 18 h, 12 h, 6 h, 3 h, 2 h, 1 h, 45 min or 30 min, more preferably in a microbial cell. The invention further relates to a nucleic acid comprising a nucleic acid sequence encoding the alcohol acyl transferase of the invention, or a complementary sequence thereof, and a vector or gene construct comprising the nucleic acid of the invention. Further provided by the present invention is a host cell comprising the vector or gene construct of the invention, and a transgenic non-human organism comprising the nucleic acid of the invention, the vector or gene construct of the invention, or the host cell of the invention.

  • Patent number: 10773957
    Abstract: The invention pertains to a method for recovering HCl from a HCl containing gas stream wherein a HCl containing gas stream with a temperature of ?20 to 25° C. is provided to an adiabatic absorption unit where it is contacted with water as an absorbent, resulting in the formation of a top gas stream and a aqueous HCl product solution, wherein the temperature of the top gas stream is at least 70° C. and wherein the aqueous HCl product solution has a HCl concentration in the range of 5-20 wt. %. It is preferred for the HCl-containing gas stream to be derived from a hydrogenation step wherein a feed comprising monochloroacetic acid (MCA) and dichloroacetic acid (DCA) is reacted with hydrogen to form a HCl-containing gas stream and a product stream comprising MCA and a reduced amount of DCA. The HCl product solution is preferably diluted to a concentration of 1-8 wt.

  • Patent number: 9505693
    Abstract: The process of the present invention pertains to a process wherein a liquid feed comprising monochloroacetic acid, dichloroacetic acid, and optionally acetic acid and/or trichloroacetic acid is subjected to a catalytic hydrodechlorination step by contacting it with a source of hydrogen in the presence of a solid heterogeneous hydrogenation catalyst situated in a fixed catalyst bed, wherein the liquid feed is fed to the top of avertical tubular reactor at a superficial mass velocity of between and 10 kg/s per square meter of the horizontal cross-section of the vertical tubular reactor and a rate of between 250 and 3,000 kg/hr per m of said catalyst bed, wherein the source of hydrogen is fed to the top or bottom of the vertical tubular reactor at a rate of between 0.025 to 0.

  • Patent number: 9505694
    Abstract: The present invention pertains to a process for the purification of a substantially water-free liquid feed comprising monochloroacetic acid, dichloroacetic acid, optionally acid chlorides, optionally anhydrides, and optionally acetic acid, which comprises the steps of (a) adding water to the liquid feed so that a liquid feed is obtained comprising between 0.01 and 5% by weight of water, based on the total weight of the liquid feed, and (b) subsequently subjecting the liquid feed obtained in step (a) to a catalytic hydrodechlorination step by contacting it with a source of hydrogen to convert the dichloroacetic acid into monochloroacetic acid in the presence of a solid heterogeneous hydrogenation catalyst comprising one or more metals of Group VIII of the Periodic Table of the Elements deposited on a carrier.

  • Patent number: 9242916
    Abstract: The invention relates to a process wherein a stream comprising dichlorohydrin, water, and HCI is separated into a stream which is rich in dichlorohydrin and low in HCI and an aqueous HCI stream which is low in dichlorohydrin. The process involves the distillation of the mixture comprising dichlorohydrin, water, and HCI with an amount of water being added before and/or during the distillation such that the water concentration during the distillation is on the line D-E, or to the right thereof, in the phase diagram of FIG. 1.
