Abstract: A handheld appliance and a beater attachment therefor. The handheld appliance may include a housing having a cavity with an opening and an electronic component in the cavity. A power cord may be coupled to the electronic component. The handheld appliance may include a cord storage compartment coupled to the housing to close the opening. The cord storage compartment may include a central support portion. The power cord may be configured to be at least partially wrapped around the central support portion. The cord storage compartment may be movable relative to the housing between: (1) a closed position wherein the central support portion is located within the cavity of the housing; and (2) an open position wherein the central support portion protrudes from the housing to allow adjustments to an amount of the power cord that is wrapped around the central support portion.

Abstract: Preparation method of fosamprenavir derivatives is disclosed. The compound shown by formula II or its ammonium salt is reacted with a metal ion source in solvent to obtain the compound shown by formula Iii. After isolating and purifying, the compound shown by formula III is catalytically reduced to the compound shown by formula I. In the formula, X is metal ion. Preferably, the metal ion source is a calcium ion source, sodium ion source, or potassium ion source, and X is calcium ion, sodium ion, or potassium ion. The solvent is methanol, ethanol, n-propanol, isopropanol, n-butanol, or sec-butanol. The catalytic reduction is carried out by using hydrogen as a reducing agent in the presence of palladium on carbon catalyst. The ammonium salt is methylamine salt, dimethylamine salt, ethylamine salt, diethylamine salt, isopropylamine salt, dibutylamine salt, dipropylamine salt, t-butylamine salt, or dicyclohexylamine salt.
