The invention provides a ganciclovir sodium synthesis process which comprises the following steps: taking diacetylguanine as a raw material, mixing and heating diacetylguanine with p-toluene sulfonic acid and an N, N-dimethylformamide-methanol solution, then adding triacetylmethoxyglycerol for condensation, and adding methanol and an adsorbent in the condensation process so that the reaction is balanced and positively moved, the generation of triacetyl ganciclovir isomers is reduced, the product purity and yield are improved, and finally reaction is performed in a sodium hydroxide ethanol aqueous solution to obtain ganciclovir sodium. The ganciclovir sodium produced by the synthesis process is easy to operate, low in cost and easy to industrially produce.
