Fast to rise, mixture gradually becomes celadon by canescence, when temperature rises to 180-190 DEG C, reactant micro-boiling, maintains the temperature
Degree；When absorb the water of HCl gases in it is acid when, continue to raise temperature, controlling reaction temperature is no more than 210 DEG C, when not there is chlorine
Change hydrogen to release, then stop heating, reaction finishes；
After S2, mixture are slightly cold, thereto plus NaOH solution is extracted and suitably heated, and leaching liquor is quickly stirred, makes to mix
Gradually dissolving is scattered for compound, place cooling or it is on the rocks be cooled to below room temperature rapidly, after the clarification of upper strata red tan solution, progress
Filter, repeatedly washed with distilled water to washing lotion and be bordering on water white transparency；
S3, under fast stirring, hydrochloric acid is added in the above-mentioned a- Nafusakus aqueous solution slowly and is acidified, acid adding regulation
During pH=1-2, there is white precipitate generation, filter to obtain crude product a- methyl α-naphthyl acetates；Still contain a small amount of a- methyl α-naphthyl acetates in filtrate, collect, treat
Concentration；
S4, after crude product a- methyl α-naphthyl acetates being added water heating boil, when being cooled to white powder precipitation, solution upper strata has
A little dark oil thing occurs, and above-mentioned solution is filtered while hot, and crystallization is produced after filtrate cooling, then through filtering, being drying to obtain essence
A- methyl α-naphthyl acetates processed, it is white powdery solids.
Further, extracted in step S2 in remaining pitch shape naphthalene slag, still there are many unreacted naphthalene recoverables,
Steam distillation can be used to reclaim.
Further, hydrochloric acid is made after being absorbed with water in the hydrogen chloride gas discharged in step S1 in synthetic reaction.
Further, in step S4 in filtered mother liquor or residue, all also contain considerable amount of methyl α-naphthyl acetate, do at concentration
Reason is utilized, and 1%a- Nafusaku solution can will be also made after mother liquid disposal.
Further, naphthalene and chloroacetic mol ratio are 1.5 in step S1, reaction time 20h, catalyst aluminium powder dosage
For the 1.6% of material gross mass.
The beneficial effects of the invention are as follows：Using the seed growth conditioning agent made by the present invention, mainly for rice class list
Cotyledon plant and the seedling of cucumber class dicotyledon, the rice shoot that brings out is blackish green, healthy and strong, well developed root system, be not subject to low temperature and
The influence of wet injury.
