The invention discloses a method for preparing a flame-retardant orange essential oil-based vinyl ester resin monomer. The method comprises the following steps: adding an unsaturated anhydride into a reactor so as to be completely fused, and dripping orange essential oil; performing reduced pressure distillation to remove impurities, thereby obtaining an intermediate product orange essential oil-based anhydride; dripping distilled water, carrying out a condensate reflux reaction, thereby preparing an orange essential oil-based dicarboxylic acid; adding DOPO into the orange essential oil-based dicarboxylic acid prepared in the first step, and heating and reacting so as to obtain a flame-retardant orange essential oil-based dicarboxylic acid; adding the flame-retardant orange essential oil-based dicarboxylic acid and epoxy chloropropane into a reactor, adding a catalyst A, adding sodium hydroxide and calcium oxide with the same mole number as carboxyl, stirring, performing suction filtration so as to obtain the filtrate, and performing rotary evaporation to remove excessive epoxy chloropropane, thereby obtaining flame-retardant orange essential oil-based epoxy resin; and adding the flame-retardant orange essential oil-based epoxy resin, a catalyst B and a polymerization inhibitor into a reactor, heating, and dripping acrylic acid into the reactor, thereby preparing the flame-retardant orange essential oil-based vinyl ester resin monomer.

The invention discloses a method for preparing activated carbon from penicillin or terramycin strain residues. The method comprises the steps of: crushing strain residues, sieving by a 20-meshed sieve, uniformly mixing the strain residues with a solution prepared according to different activation ratios, soaking at a constant temperature for 24 hours, drying in an oven at the temperature of 105-110 DEG C, placing in a temperature resistant sealed container to prevent oxidization and incineration, placing the sealed container in an activating and carbonizing furnace, heating to an activation temperature, activating at the constant temperature for set time, washing the activated strain residues with hydrochloric acid, then washing with water to be neutral, drying at the temperature of 105-110 DEG C for 2-3 hours, and cooling to room temperature to obtain the strain residue activated carbon. According to the invention, prepared activated carbon is high in specific area, rich in micropores and mesopores and excellent in adsorbing performance; and waste terramycin strain residues from a pharmaceutical factory are utilized to prepare activated carbon, thus the resource, reduction and harmless treatment of the waste strain residues are effectively realized, and the social benefit is significant.

A preparation method of orange oil-based unsaturated resin monomer, which comprises reacting a certain amount of orange essential oil with unsaturated carboxylic acid or acid anhydride to prepare orange oil-based unsaturated carboxylic acid or acid anhydride; and then making orange oil-based unsaturated Carboxylic acid or acid anhydride is converted into sodium salt, and then reacted with chloropropene to synthesize orange oil-based unsaturated resin monomer. The orange oil-based unsaturated resin monomer prepared by the invention is used in the field of unsaturated resins, and after being mixed with other unsaturated resin monomers in a certain proportion, corresponding products and materials can be prepared through ultraviolet light curing and heating curing. The unsaturated resin monomer made from orange essential oil has low viscosity (500-1000mPa s) and high iodine value (200-270), which has the potential to replace the conventional non-environmental friendly diluent styrene, and the product is expected to improve the traditional Unsaturated resin has the disadvantages of poor toughness and poor weather resistance, and at the same time improves the comprehensive performance of unsaturated resin copolymer materials.
