Process and apparatus for transferring air-sensitive substances
View Patent ↗A process is provided for transferring and releasing substances which are air-sensitive or moisture-sensitive or light-sensitive, or air-sensitive and moisture-sensitive, or air-sensitive and light-sensitive, or moisture-sensitive and light-sensitive, or air-sensitive, moisture-sensitive and light-sensitive, at least one substance ( 20 ) which is air-sensitive or moisture-sensitive or light-sensitive, or air-sensitive and moisture-sensitive, or air-sensitive and light-sensitive, or moisture-sensitive and light-sensitive, or air-sensitive, moisture-sensitive and light-sensitive. The process comprises removing the substances after preparation under a protective gas atmosphere, from a synthesis chamber, wherein, during said removing, the substances are surrounded by at least one means ( 32, 34 ) for protecting the substances and then transferring the substances to at least one test reactor ( 50, 60 ), wherein the transfer takes place in a protective-gas-free chamber and at least one substance ( 20 ) is freed in the test reactor ( 50, 60 ) from the means ( 32, 34 ) protecting it using at least one apparatus or by means of at least one process.
1. An apparatus comprising:
(a) a vessel with an opening, configured to accept a substance through the opening and further configured for the opening to be sealed;
(b) a synthesis chamber configured to accept the vessel and further configured to establish or maintain a protective gas atmosphere when the vessel is present;
(c) a test reactor configured to accept the vessel, and further configured to establish or maintain a protective gas atmosphere when the vessel is present;
(d) means located within the test reactor to destroy the vessel in order to open the vessel and release the substance into the reactor, the means to destroy the vessel comprising a solvent to dissolve and destroy the vessel, a rotating stirring element to impact and destroy the vessel, or a mechanism to propel the vessel against the reactor to destroy the vessel; and
(e) means for transferring the vessel, when sealed, from the synthesis chamber to the test reactor.
2. The apparatus of claim 1 , wherein the vessel, when sealed, is air, moisture, or light impervious.
3. The apparatus of claim 1 , wherein a gas-tight cover is used to seal the opening of the vessel.
4. The apparatus of claim 3 , wherein the gas-tight cover is formed of the same material as the vessel.
5. The apparatus of claim 3 , wherein the means to destroy the vessel destroys the gas-tight cover in order to open the vessel.
6. The apparatus of claim 1 , wherein the vessel is sealed by covering the opening with a film, or a curable or viscous material.
7. The apparatus of claim 6 , wherein the means to destroy the vessel destroys the film, or curable or viscous material in order to open the vessel.
8. The apparatus of claim 1 , wherein the synthesis chamber is a glove box.
9. The apparatus of claim 1 , wherein the protective gas is argon, nitrogen, helium or mixtures thereof.
10. The apparatus of claim 1 , further comprising a lock connected to the test reactor, the lock being configured to establish a protective gas atmosphere around the vessel prior to the vessel being transfered into the test reactor.
11. The apparatus of claim 1 , wherein the vessel is made from glass, ceramic, plastic, metal, or a composite material.
12. The apparatus of claim 1 , wherein the vessel is made from a material that will dissolve in a solvent.
13. The apparatus of claim 1 , wherein the means for transferring the vessel is a fully-automatic apparatus or a robot.
