摘要:
The invention relates to a method for the non-therapeutic treatment of animals selected from the group consisting of poultry, pigs and fish. The treatment comprises orally administering at least one ß-alanine compound to the animals in an amount of between 2 and 55 mmol/kg dry weight of said feed for the treatment of poultry and fish and between 2 and 25 mmol/kg dry weight of said feed for the treatment of pigs. These amounts of the ß-alanine compound are used for reducing the conversion ratio or for increasing the bodyweight gain of the animals. The ß-alanine compound is in particular ß-alanine. In prior art methods higher amounts were used resulting also in a reduction of the feed conversion ratio but this to the detriment of the bodyweight gain.

A method for the stabilization of an aqueous choline hydroxide solution includes optionally, adding a first stabilizer of a dithionite salt or a dialkylhydroxylamine to an aqueous solution containing reactants that will produce an aqueous choline hydroxide solution; and after the aqueous choline hydroxide solution is formed, adding a second stabilizer of a dithionite salt or a dialkylhydroxylamine to the aqueous choline hydroxide solution. The stabilized choline hydroxide solution may include choline hydroxide, water, and a dithionite salt and/or a dialkylhydroxylamine as a stabilizer present in an amount of about 100 ppm to about 2000 ppm by weight of the stabilized choline hydroxide solution.
摘要:
The present invention relates to a method and an arrangement for separation and recovery of at least one carboxylic acid and furfural from a dilute aqueous mixture thereof. In the method of the present invention a dilute aqueous mixture comprising at least one carboxylic acid and furfural is extracted with methyltetrahydrofurane, and at least one carboxylic acid and furfural are recovered. The arrangement of the present invention comprises an extraction unit 302 for carrying out extraction of at least one carboxylic acid and furfural from dilute aqueous mixture with methyltetrahydrofuran, connected to distillation unit 307 for carrying out distillation of the extract 305 from the extraction unit 302, and connected to acids distillation unit 320 for carrying out distillation of the bottom stream 308 from the distillation unit 307 to separate at least one carboxylic acid and furfural.
摘要:
The present invention relates to dissolved silicate compositions in which the dissolved silicate is stabilized by at least two selected osmolytes and is therefore bioavailable. The composition and its dilutions are stable over a long period of time and are used in a wide field of applications for the benefit of living organisms such as plants, animals and humans.

摘要:
In a process for the aqueous suspension polymerization of vinyl chloride, alone or in mixture with other monomers, in the presence of at least one of dialkylperoxydicarbonate, peroxyester and diacyl peroxide, the polymerization composition according to the invention comprises at least one dialkylhydroxylamine as a shortstopping agent along with a totally or partially hindered phenolic antioxidant.
摘要:
A process is described for obtaining free flowable, carrier free powders from aqueous solutions of deliquescent quaternary ammonium compounds in a two step process, comprising a drying and a powder mixing step. The excellent free-flowing and stability characteristics of the final product could only be obtained when among possible other additives at least one univalent metal fatty acid salt is added to the liquid phase in the drying step and at least one multivalent metal fatty acid salt in the powder mixing step. A surprising synergy was observed between these additives when applied as described in the present invention.
摘要:
Disclosed is a process for the preparation of primary, secondary and tertiary amines via a catalytic hydrogenation of unsubstituted, N-substituted, and N,N- disubstituted amides. The amide is led, together with an auxiliary amine, in vaporised form in a hydrogen containing gas flow over the catalyst. The process can be carried out at relatively low pressures, between 2 and 50 bars, using typical hydrogenation catalysts like CuCr-type catalysts. The amine is obtained with high yield and high selectivity. The process can be carried out in a continuous fixed bed reactor.
