Usage

General Description

Pentachlorophenol acetate is a chemical compound that is a derivative of pentachlorophenol, which is commonly used as a wood preservative. It is a white crystalline solid that is soluble in organic solvents. Pentachlorophenol acetate is used in the treatment of utility poles, railway ties, and marine pilings to protect the wood from decay and insect damage. However, it is considered to be toxic to humans and the environment, and exposure to this chemical can lead to adverse health effects such as skin and eye irritation, respiratory problems, and damage to the liver and kidneys. Due to its potential hazards, the use of pentachlorophenol acetate has been regulated in many countries.

Preparation method of levocarnitine

The invention provides a preparation method of levocarnitine. The preparation method comprises the following steps: taking epoxy chloropropane as a starting material, then carrying out amination, cyaniding and carrying out ester exchange under the action of lipase CALB to obtain corresponding chiral ester, then carrying out alkaline hydrolysis and acidification, and then removing chlorine ions under the action of strongly alkaline resin, so that the levocarnitine finished product is obtained. In the invention, acid resin is used in an ester exchange process, and recemization can be realized, so that yield and optical purity of the levocarnitine are improved.

Selective esterifications of alcohols and phenols through carbodiimide couplings

Esterification of carboxylic acids capable of forming ketene intermediates upon treatment with carbodiimides permits the selective acylation of alcohols in the presence of phenols lacking strong electron-withdrawing groups. The selectivity of acylations involving highly acidic phenols could be reversed through the addition of catalytic amount of acid. Esterification of other carboxylic acids was found to proceed through the formation of symmetric anhydrides and provide the opposite chemoselectivity. In both cases the relative acylation rates of substituted phenols are consistent with a reaction mechanism involving an attack of phenolate anions on electrophilic intermediates such as ketenes and symmetric anhydrides, with the carbodiimides serving both as an activating reagent and as a basic catalyst.
