An amino acid broad-spectrum medicinal fertilizer without environmental pollution contains the mixture of copper zine manganese iron magnesium salts of mixed amino acid (13-20 wt.%), glycine hydrochloride (2-6), kurarinone (0.1-1), mangostin (0.06-0.6), veratrine (0.3-1), bioactive synergist (0.06-0.6), Chinese medical stone extract (1.5-2.5), surfactant (0.5-5) and filler (the rest). It has bothantibacterial and nutritive functions for raised yield and improvement quality of crops.

The invention relates to a process for the preparation of anagrelide, and for the preparation of intermediates for use in preparing anagrelide. The invention also relates to the intermediates per se, in particular compounds of Formula (V):where R constitutes a suitable leaving group, which may not be hydrogen. The R group may be selected from: (i) —SiR13, (ii) —CH2Ar, (iii) —COOR2, and (iv) sulfonates such as —SO2R3.

The invention discloses a method for preparing chiral alpha-alkyl substituted glycine hydrochloride. The method comprises steps of: selecting commercialized or easily prepared tert-butyl glycinate as an initial raw material; inducing alpha position chiral alkyl substitution through a chiral adjuvant (S) camphor; carrying out chemical split to obtain alpha-alkyl substituted glycine ester; and finally hydrolyzing to obtain optically pure alpha-alkyl substituted glycine hydrochloride. R represents C1-C12 saturated or unsaturated alkyl, or C1-C12 saturated or unsaturated alkyl substituted phenyl. The method uses cheap and easily available raw materials, has high reaction yield, stable technical condition, simple operation and no pollution; the obtained product has an optical purity greater than 99%; therefore, the invention provides a new idea and method for large-scale production of amino acid with high chiral purity.

The invention discloses a preparation method for a deodorization sterilization sheet used for sterilizing infectious medical waste. The preparation method comprises the following operation steps: (1)preparing sodium aluminate solution, then, regulating the pH (Potential of Hydrogen) of the solution, heating mixed liquid, carrying out thermal insulation reaction, cooling to room temperature, carrying out centrifugation to obtain sediments, and preparing a water insoluble carrier; (2) after polyethylene glycol 6000 is heated and fused, adding sodium lignin sulfonate, sodium bicarbonate and N-octyl diamine ethyl glycine hydrochloride into the polyethylene glycol 6000, cooling to room temperature, and smashing to obtain a water-soluble carrier; (3) evenly mixing the water insoluble carrier, the water-soluble carrier, citric acid and sodium dichloro cyanurate, slowly adding absolute ethyl alcohol and 4-dodecalactone into the mixture to be evenly stirred, adding into a granulator to be granulated and dried, and pressing to obtain the deodorization sterilization sheet. The deodorization sterilization sheet prepared with the preparation method has the advantages of obvious sterilization effect, no odorous pungent smell, and odorous smell in the infectious medical waste can be effectively prevented from emitting.
