  • Patent number: 11518749
    Abstract: A process for the continuous distillative separation of mixtures comprising morpholine (MO), monoaminodiglycol (ADG), ammonia, water and methoxyethanol (MOE), obtained by reacting diethylene glycol (DEG) with ammonia, wherein ammonia, water, ADG and DEG are removed by distillation and the resulting stream comprising MO and MOE is supplied to a distillation column K40 in which at a top pressure of from 20 to 2000 mbar MO, MOE and organic products having a boiling point 128° C. (1.013 bar) are removed via the bottom and organic products having a boiling point 128° C. are removed overhead, and also MO is removed via a side draw, where K40 is equipped with an evaporator for heating the bottoms, into which is fed heating vapor having a pressure of from 1 to 10 bar.

  • Patent number: 11214555
    Abstract: A process for the depletion of 2-methoxyethanol (MOE) from a mixture comprising predominantly morpholine (MO) (crude morpholine), wherein crude morpholine is distilled in a distillation column in the presence of an alkali metal compound of the general formula M+[RO?] (M+ is alkali metal cation and R is hydrogen (H), methyl, ethyl, propyl, isopropyl, n-butyl, isobutyl, sec-butyl or tert-butyl), where MO and a compound of the general formula R—OH are distilled off and an alkali metal methoxyethoxide of the general formula M+[MeOEtO?] is obtained in the bottom of the column.

  • Patent number: 8652092
    Abstract: The invention relates to applicators (1) for implantation of an implant, having a cylinder (2) and a plunger (3) displaceably mounted therein, which plunger (3) has a pusher plunger (31) for pushing the implant out of a cannula, the cannula being mounted on a cylinder part, the cylinder part (4) being movably guided in the cylinder (2), there being provided a gear mechanism (5) which couples the plunger (3) to the cylinder part (4), a movement of the plunger (3) relative to the cylinder (2) being converted into an opposite movement of the cylinder part (4).

  • Publication number: 20120024689
    Abstract: Processes for the continuous fractional distillation of a mixture comprising morpholine (MO), monoaminodiglycol (ADG), ammonia and water from a reaction of diethylene glycol (DEG) with ammonia, the process comprising: (i) separating off ammonia from the mixture at a top of a first distillation column K10; (ii) feeding a bottom fraction from the first distillation column to a second distillation column K20, wherein water and an organic product are separated off at a top of the second distillation column at a top temperature of 45 to 198° C. and a pressure in the range from 0.1 to 15 bar; (iii) feeding a bottom fraction from the second distillation column to a third distillation column K30, wherein morpholine and an organic product having a boiling point of <140° C. (1.013 bar) are separated off at a point selected from a top and a side offtake of the third distillation column, and monoaminodiglycol and an organic product having a boiling point of >190° C. (1.
