Details:
18-Crown-6 is a slightly yellow solid powder.It is a chemical substance with a molecular formula of C12H24O6. A colorless viscous liquid, also known as a macrocyclic ether, is a macrocyclic compound containing a plurality of oxygen atoms. When naming, the total number of atoms contained in the ring is marked before the word "crown", and the number of oxygen atoms contained in it is marked after the name. This was unexpectedly discovered by DuPont's Pedersen in 1967 and found that these compounds have many unusual properties.

Function & Application
One of the most important features of crown ethers is the formation of stable complexes with various metal salts, ammonium salts, and organic cationic compounds.
With this property, various salts can be dissolved in an organic solvent.
For example, as a phase transfer catalyst, many reactions which are difficult to react or even occur under conventional conditions can be smoothly carried out, and such reaction rates are fast, the conditions are simple, the operation is convenient, and the yield is high. For example, the yield of the condensation reaction of benzoin in an aqueous solution is extremely low, and if 7% of a crown ether is added to the aqueous solution, a benzoin having a yield of 78% can be obtained.

Production Inspection Process:
Our Group service includes regular and thorough inspections throughout the manufacturing process, eliminating the need to employ additional quality control inspectors.
- Raw material before any production begins
- Pre-production samples to ensure specifications are being met
- In-process to confirm that standards are maintained
- Pre-shipping to ensure that the product arrives to the customer exactly as expected and is packaged
correctly to prevent any damage in transit.
We can help operating split shipments, meeting the factory minimum quantity but ship them in 2 or 3 shipments with required gaps among. This allows you to move stock through your business without taking up space and capital.
We will arrange the subsequent shipments from our factory to your warehouse.
We can consolidate your small orders from multiple factories, delivering all at the same time to you or your customers,using the most cost-effective route available. At the time of order placement, we will offer details to you about the volume of each component part and what size container will be used.
We can offer the complete package from concept to delivery; arranging everything up until products arrive at your own door or distribution hub.
Delivery can be offered.
- Utilizing your own freight-forwarder
- FOB to a port in China
- CIF to a port near you
Whether you have your own freight-forwarder or you would like to organize shipment; whether you require delivery FOB in China or CIF to a port near you, we are glad to quote and supply whichever way you choose. Please feel free to discuss all options with us.
