The present invention describes a process for the industrial production of L-carnitine, comprising the enantioselective reduction of an alkyl 4-chloro-3-oxobutyrate or 4-chloro-3-oxobutyramide. The optically active 3-hydroxy derivative thus obtained is reacted with trimethylamine, obtaining crude L-carnitine, which is then finally purified. The catalyst used for the reduction is a complex of ruthenium bound to a penta-atomic bis-heteroaromatic system. The reduction reaction, performed in controlled conditions of hydrogen pressure, substrate concentration, temperature, and substrate: catalyst molar ratio, enables 4-chloro-3-hydoxybutyrate or 4-chloro-hydroxybutyamide to be obtained in a high yield. The process described, which leads to L-carnitine being obtained, is easily applicable on an industrial scale.

An electric rheologic liquid contains the granular composition suspended in an electrically insulative hydrophobic liquid. Said granular composition contains a metallic salt M1xM22-2xTiO(C2O4)2, where M1 is chosen from Ba, Sr and Ca and M2 is chosen from Rb, Li, Na and K, and a cocatalyst chosen from urea butylamide and ethylamide.

The invention discloses a new synthesizing technique of chiral drug (S)-alpha-ethyl-2-oxo-1-pyrrolidine acetamide ( left Piracetam) intermediate (S)-(+)-2-aminobutanamide hydrochlorate, which comprises the following steps: adopting 2-brobutyrate as initial raw material; aminating; esterifying; ammonolyzing; detaching; looping; obtaining the object compound; making mixed rotary free alkaline (+-)-2-aminobutanamide; adopting half-quantum resolution method to connect chemical detaching salt to evolve salt; removing the detaching agent through alkalization; obtaining the (S)-(+)-2-aminobutanamidehydrochlorate with optical activity; using the mother liquor to make the product. The invention improves the receiving rate and saves the cost of raw material with simply technical operation and low cost, which resolves the resolved mother liquor after racemic action again to reduce the pollution of environment, therefore fitting for industrialized manufacturing.

The present invention provides methods, compositions and devices for stabilizing the extracellular nucleic acid population in a cell-containing biological sample using butanamide.
