一般描述
1,1,1,2-Tetrafluoroethane is used as a trifluorovinylating agent in organic synthesis. It is identified as a potential refrigerant used in place of chlorofluorocarbons. 1,1,1,2-Tetrafluoroethane can also be used as a solvent and medical propellant for a wide range of applications. It is used to extract materials of natural origin like natural flavors, fragrances, and nutraceuticals.
应用
1,1,1,2-Tetrafluoroethane can be used:
- As a solvent in the preparation of cross-linked polymer microspheres through the dispersion polymerization method.
- As a porogenic solvent in the preparation of porous polymethacrylate monolith via free radical polymerization.
- In the synthesis of trifluorovinyllithium, a key intermediate for the preparation of 2-halo-2,3-dideoxy-arabinose derivatives of biological importance.
包装

This study investigated the effect of different active pharmaceutical ingredients (API) on aerosol electrostatic charges and aerosol performances for pressurized metered dose inhalers (pMDIs), using both insulating and conducting actuators. Five solution-based pMDIs containing different API ingredients including: beclomethasone dipropionate

Blood-air and tissue-blood coefficients (lambda) are essential to characterize the uptake and disposition of volatile substances, e.g. by physiologically based pharmacokinetic (PBPK) modelling. Highly volatile chemicals, including many hydrofluorocarbons (HFC) have low solubility in liquid media. These characteristics pose challenges

High-speed laser imaging (HSLI) is the preferred technique to characterize the geometry of the plume in pressurized metered dose inhalers (pMDIs). However, current methods do not allow for simulation of inhalation airflow and do not use drug mass quantification to

Free astaxanthin one-solvent extractions with ethanol, acetone, and liquid 1,1,1,2-tetrafluoroethane from raw and lactic acid fermented (ensilaged) shrimp residues were investigated. The total carotenoid recovery from ensilaged shrimp wastes was higher than that from non-ensilaged ones as assessed by HPLC
