At a competitive price, Dakenchem provides world-class custom synthesis services of a wide range of compounds on a milligram to kilogram scale.
What does the custom synthesis mean?
Custom synthesis refers to the process of synthesizing compounds specifically for a certain client based on specifications at their scale. Reproduction of known synthetic pathways (the simplest and quickest method for performing custom synthesis) and design of functional (macro)molecules are the two types of custom synthesis.
Outsourcing in general, and custom synthesis, have grown rapidly over the last two to three decades.
Why need a custom synthesis services?
Here, customers can get a specific and unique chemical produced on their demand with the specific features such as scale, purity, and methods that they require. Moreover, custom synthesis helps them specifically in saving money, time, and effort.
What chemicals are the custom synthesis?
Succinic acid is a water-soluble colorless crystalline solid that is utilized to make a wide range of bulk chemicals, polymers, and resins. This molecule is an important intermediate in the production of organic chemicals.
Succinic acid is used in the production of pharmaceuticals, agricultural and food products.
Dichloro(1,5-cyclooctadiene)palladium(II) is a yellow crystalline powder that readily absorbs moisture. It is insoluble in water but soluble in dichloromethane and glacial acetic acid. It can be used as a precious metal, noble metal, heterogeneous, or homogeneous catalyst. This chemical has mild reaction conditions, strong temperature tolerance, high activity, and excellent selectivity.
The process
Industrial free radical polymerization can be carried out in four different ways.
- Bulk polymerization
Only monomers and initiators are present in the reaction mixture. This is accomplished by introducing a soluble initiator to pure monomers in the liquid state. The disadvantages of this approach are the high viscosity in the mixture and the difficulty in controlling when the polymerization reaction is exothermic because no solvent is present.
- Solution polymerization
Monomers are dissolved in an initiator-containing non-reactive solvent. Heat transfer is aided by the presence of a solvent, which also reduces viscosity. To avoid chain transfer reactions, the solvent must be carefully chosen in this approach.
- Suspension polymerization
This approach involves mechanically dispersed monomers in a non-compatible liquid usually water. Monomer droplets will occur because of this. The polymer will be generated in the form of granular beads if the process of polymerization of monomer droplets employing a monomer soluble initiator is carefully regulated. The efficiency of heat transfer and the ability to avoid viscosity build-up during polymerization are two advantages of this method.
- Emulsion polymerization
Water is utilized as the dispersion media in emulsion polymerization, which is like suspension polymerization. The initiator is soluble in the aqueous phase (water) rather than in a monomer droplet, which distinguishes it from suspension polymerization. The essential ingredients in this method are monomers, water, a water-soluble initiator, and an emulsifying agent (surfactant). An emulsifying agent, such as soap or detergent, is used to disperse monomers in the aqueous phase. These surfactants form aggregates or micelles in aqueous media. Initiator radicals usually of the redox type are generated in the aqueous phase and diffuse into micelles with monomer molecules. Polymerization takes place inside of the micelle, resulting in a swollen polymer particle.
