这种接枝共聚物一旦析出并干燥以后，在常温下不溶于包括苯甲醇、间甲苯酚在内的大多数溶剂，但却易溶于极性较强的溶剂如98％的甲酸。

The optimun technological conditions were studied on the synthesis of 9-flourenylmethanal by the reaction of flouren and ethyl formate , and the synthesis of 9-flourenylmethanol by the reaction of 9-flourenylmethanal and methanal with sodium ethylate as catalyst.

研究了乙醇钠为催化剂，由芴与甲酸乙酯合成芴甲醛，再由芴甲醛与甲醛合成苯甲醇的工艺条件，结果表明：合成芴甲醛时，当芴为 16g时，催化剂乙醇钠 4 。

In the presence of NaH and in DMF, the acyclic crown ethers 1a and 1b were synthesized by the reaction of di-or triethyleneglycol ditosylate and o-methoxymethoxybenzyl alcohol, which was obtained from salicylaldehyde via the protection of the hydroxyl group with chloromethyl methyl ether followed by the reduction of the formyl group with NaBH4. The hydrolysis of 1a and 1b with dilute hydrochloric acid provided the diphenolic type acyclic crown ethers 2a and 2b respectively in good yield.
