What is Cyclopentanethiol?
Cyclopentyl mercaptan belongs to a class of organic compounds called alkyl mercaptans. These are organic compounds containing mercaptan functional groups linked to alkyl chains. Cyclopentyl mercaptan is a compound with onion, celery and citrus flavor.
It is synthesized from cyclopentyl bromide and potassium hydrogen sulfide. Or synthesized from cyclopentanone dimethyl dithioacetaldehyde and four moles of an alkali metal; It can also be prepared from sulfurized cyclopentyl naphthyl in the presence of a metal aluminosilicate catalyst.
Cyclopentanethiol has been used as a food flavoring. It is a pharmaceutical intermediate.
Food spice. For bakery products, meat products, soups, dairy products, condiments, cereals, all 0.1mg/kg.
Application of Cyclopentanethiol
CN202110291866.2 reports a preparation method of silver telluride quantum dots with high brightness and narrow half-maximum width. By regulating the activity of the silver precursor generated by the reaction of silver thiol and phosphine, and using the tellurium precursor synthesized in the air, silver telluride quantum dots with excellent performance were prepared. The technical solutions adopted by the present invention include:
1) Under an inert atmosphere, add the silver source and thiol to the solvent, raise the temperature to the first temperature, add the organic phosphine, and obtain solution A;
2) Preparation of tellurium precursor: Mix tellurium powder and organic phosphine and heat in air to obtain solution B;
3) Under an inert atmosphere, heat solution A to the second temperature, hot-inject freshly prepared solution B into solution A, rapidly cool to the third temperature, react for 1 to 40 minutes, cool to room temperature, and obtain telluride after purification. Silver quantum dots.
The activity of the silver precursor can be controlled by adjusting the type and amount of thiol and organic phosphine in step 1). The preferred molar feed ratio of thiol, organic phosphine and silver source is 7:1:1.
The size of the quantum dots during nucleation is adjusted by adjusting the molar ratio of the silver source in step 1) to the tellurium precursor in step 3), thereby controlling the emission wavelength.
The mercaptan in step 1) can be selected from at least but not limited to alkyl mercaptan having 8 to 18 carbon atoms, cyclohexane mercaptan and cyclopentyl mercaptan.
