Procedure: Pentadecanoic acid (24.2g) was treated with thionyl chloride (13.1g) at 80°-90° C. Pentadecanoyl chloride, thus obtained, was added slowly under ice cooling into the mixture of β-phenoxyethylalcohol (13.8g), pyridine (10.3g) and benzene (100ml) with stirring. After having been stirred, the reaction mixture was treated with an ordinary method (washed with dilute hydrochloric acid, the benzene layer was dried over Glauber's salt, and then benzene was removed under reduced pressure, giving a crude product). Solid (33g) was obtained. The solid was recrystalized from n-hexane, from which it formed colourless crystals (26g), m.p. 45.0°-47.0° C., of β-phenoxyethyl pentadecanoate.

Procedure: In a one L (liter) two-necked flask were placed 160.0 g (0.66 mol) of pentadecanoic acid and 200 milliliter (mL) of cyclohexane, and the flask was equipped with a 100 mL dropping funnel containing 83.3 g (0.7 mol) of thionyl chloride and a reflux tube. Then, the pentadecanoic acid was completely dissolved under heating and stirring of the flask in an oil bath at 80° C. Thereafter the thionyl chloride was added dropwise over a period of 2 hours, and further the oil bath was maintained at 80° C. for one hour. From the resultant reaction mixture were removed the cyclohexane and the thionyl chloride under reduced pressure by means of an aspirator. The resultant crude reaction product was subjected to vacuum distillation. Thus 110.0 g (0.42 mol) of pentadecanoyl chloride was obtained in a yield of 63.9% based on the fed pentadecanoic acid. the flask was equipped with a 100 mL under heating further the oil bath was maintained at 80° C. for one hour From the resultant reaction mixture were removed the cyclohexane The resultant crude reaction product was subjected to vacuum distillation

Procedure: Cadmium oxide (0.127 g, 1 mmol) and tetradecyl carboxylic acid (0.500 g) were reacted at 220° C. for 10 min, cooled to 90° C., a cadmium tetradecylcarboxylate (precursor) was formed. Into said system, toluene (10 ml) and mercapto-etanol (0.6 ml) was added. Then a 0.05M aqueous solution of sodium hydrogen selenide (10 ml) was added. After the system was reacted at 90° C. for 3 h, a red sol containing the mercaptoethanol-coated CdSe nanoparticles was obtained. Said sol can be dispersed stably in water, has a typical exciton absorption peak of the CdSe nanoparticles, can result in a quantum size effect and emit a fairly strong green light under the irradiation of a UV lamp.
