  • Patent number: 10919833
    Abstract: A method of synthesizing sodium formate. The method includes reacting acetaldehyde, formaldehyde, and NaOH to form a raw reaction solution which includes pentaerythritol and sodium formate. The method also includes passing the raw reaction solution to an evaporator to reduce the water content of the raw reaction solution and remove any unreacted formaldehyde from the raw reaction solution to form a concentrated reaction solution and cooling the concentrated reaction solution to form pentaerythritol crystals in suspension while retaining sodium formate in solution. Further, the method includes filtering the cooled concentrated reaction solution to remove the pentaerythritol crystals and create a mother liquor comprising the sodium formate in solution and separating the sodium formate from the mother liquor.

  • Patent number: 10450254
    Abstract: The present invention relates to a process for simultaneously consecutive preparation of polyols by base-catalyzed reaction of at least two different mid-chain aldehydes with formaldehyde. The simultaneous consecutive mode of operation makes it possible to achieve high conversions and high selectivities for both aldehydes, with additional achievement of a distinct reduction in the amount of unreacted formaldehyde remaining. This leads to improved process economics, since the energy costs for workup of the formaldehyde stream are distinctly reduced.

  • Patent number: 9677182
    Abstract: Hydrocarbons may be formed from six carbon sugars. This process involves obtaining a quantity of a hexose sugar. The hexose sugar may be derived from biomass. The hexose sugar is reacted to form an alkali metal levulinate, an alkali metal valerate, an alkali metal 5-hydroxy pentanoate, or an alkali metal 5-alkoxy pentanoate. An anolyte is then prepared for use in a electrolytic cell. The anolyte contains the alkali metal levulinate, the alkali metal valerate, the alkali metal 5-hydroxy pentanoate, or the alkali metal 5-alkoxy pentanoate. The anolyte is then decarboxylated. This decarboxylating operates to decarboxylate the alkali metal levulinate, the alkali metal valerate, the alkali metal 5-hydroxy pentanoate, or the alkali metal 5-alkoxy pentanoate to form radicals, wherein the radicals react to form a hydrocarbon fuel compound.

  • Patent number: 7767865
    Abstract: The preparation of hydroxypivalaldehyde is effected by aldolizing isobutyraldehyde with formaldehyde and subsequently working up the resulting reaction effluent by distillation, wherein the reaction effluent is fed to a distillation column which is operated at a top pressure in the range from 0.5 to 1.5 bar and in which a two-stage condensation is provided in the top region, in which the vapors are first conducted into a partial condenser operated at a temperature in the range from 50 to 80° C., whose condensate is recycled at least partly into the distillation column, and in which the vapors uncondensed in the partial condenser are fed to a downstream condenser operated at a temperature in the range from ?40 to +30° C., whose condensate is at least partly discharged.

  • Publication number: 20100152500
    Abstract: A method of preparing monopentaerythritol, dipentaerthritol, and sodium formate through high temperature condensation and cascade recrystallization is disclosed. The method lowers the energy consumption dramatically and improves the cost-effectiveness by carrying out the reaction in a non-low-temperature zone, and thereby avoiding the requirement for refrigeration. The method alleviates the difficulty of separation and improves the product quality by means of cascade separation process, and thereby avoiding the low purity from a single separation. In addition, the mother liquor obtained after each separation step is recycled to the previous step as the recycling liquor, which avoids discharging waste, increases the product yield and lowers raw materials consumption.

  • Patent number: 7569736
    Abstract: The invention relates to a process for producing monopentaerythritol of high purity and monopentaerythritol produced by the process. Formaldehyde is reacted with acetaldehyde in an aqueous solution in the presence of a strongly basic hydroxide in a conventional way. The obtained reaction mixture is evaporated to a dryness of 50-70% by weight and is thereafter cooled. Crystals of pentaerythritol thereby formed are separated off. The crystals are dissolved in water or in a water-containing mother liquor containing pentaerythritol to a dryness of 35-55% by weight. The solution is treated in a purification step whereupon monopentaerythritol of high purity is crystallized at a temperature of 40-90° C. and separated from the remaining mother liquor which is recirculated to the above mentioned step.
