Definition of molecular sieve in English:

molecular sieve

noun

A crystalline substance (especially a zeolite) with pores of molecular dimensions which permit the passage of molecules below a certain size.
Example sentencesExamples
- Butylated hydroxytoluene was added to the reaction mixture to prevent oxidation, and molecular sieves were added to keep the solvent dry.
- They have anchored bimetallic catalysts to the insides of such molecular sieves and have found that they can selectively hydrogenate cyclic polyenes.
- Since DNA molecules have much higher molecular weights than proteins, the molecular sieve used in electrophoresis of DNA must be different as well.
- Various jelly-like substances can act as molecular sieves.
- Zeolite molecular sieves can also segregate molecules of the same size but different electrical characteristics.
