The results suggested that chitinhad a good solubility in the new solvent when its at -30℃and below, but the solubilityof chitin no longer increasesd notable as the temperature reduced; The joined of urea, incertain degree, strengthened the solvency of alkali solvent to chitin. When theconcentration of sodium hydroxide is 8%～12%, Chitin had a good solubility, and theapparent viscosity of chitin solution could up to 4000 mpa·s～5000mpa·s at roomtemperature; In addition,the solubility of chitin in new solvent was high when therefrigerated time was three days and above, but the refrigerated time could not too long,otherwise, the deacetylize degree of chitin got more bigger. The properties of chitin solution were tested by revolving viscosimeter, FT-IR,X-RD and so on.

结果表明，在-30℃及以下甲壳素能很好的溶解于新溶剂中，但甲壳素的溶解度不再随温度的下降而有所增大，而是基本保持不变；尿素的加入，在一定程度上强化了强碱溶剂对甲壳素的溶解，当新溶剂中NaOH浓度为8％～12％时，甲壳素在试验温度下可以获得较好的溶解度，所得溶液在室温下的表观黏度达4000 mpa·s～5000mp·s；冷冻时间为3 d及以上时，有利于甲壳素的溶解，超过3 d，甲壳素的溶解度变化不大，另外，冷冻条件下，甲壳素在强碱溶剂中仍会发生脱乙酰化反应，冷冻时间不宜太长。

The coupling reaction of aryl iodides, bromides and chlorides with differentolefins catalyzed by catalyst 2 and 4 was studied. It was found that compounds 2 and 4 anchored on active carbon are efficient catalyst for the Heck reaction in the case of aryl bromides and aryl chlorides as substrates (Scheme 3). It is notable that catalyst 4 has higher efficiency for aryl chlorides.___^H Cat.2 or 4, Base HXSolution, 100C or 140

Industry have pointed out that because government departments have some statistical data lag, the July statistics for the month of June should be the main sales data June is "51" golden weeks after month, general sales have larger drop, and June hot Can not Stop, in a month to recorded notable increases in the remaining months of estimated increases will be more visible, thus data to illustrate this year Panyu real estate sales growth will be more convincing.

有业内人士指出，由于政府部门的数据统计有一定的滞后性，因此7月份的统计数据应主要为6月份的销售数据，6月份正是&五一&黄金周后的一个月，一般销售会有较大的回落，加上今年6月份酷热难挡，因此，在这样一个月份能够录得明显的增幅，估计在其他月份的增幅将更加明显，由此数据来说明今年番禺的房地产销售增长，将更有说服力。
