One-step extraction with polar and nonpolar mixed solvents was a method of effective comprehensive extraction for antioxidant and essential oil of rosemary (Rosmarinus officinalis L.). The method was simple on operation and was easily put into practice.

极性和非极性混合溶剂一步提取法是迷迭香抗氧化剂和精油综合提取的有效方法，操作简单，容易实施。

The results show that the resulting product can be separated by the mixture of petroleum ether, aether and acetic acid (10:10:1, V/V). Among them, the oleic acid component can be eluted by the mixed solvent of ethanol and carbon tetrachloride (35:15, V/V), and then productivity of sodium oleoyl sarcosine can be obtained.

结果表明：用石油醚：无水乙醚：冰乙酸＝10：10：1分离产物中的组分，再用无水乙醇：四氯化碳＝35：15混合溶剂洗脱制备油酸组分，进而计算油酰肌氨酸钠的产率是可行的。

In addition to the styryl, BCEA (they contain very high flammability, corrosive acid) and the flammability of the solvent dilution with 10% of the UV/EB finish, EB/UV curing materials is generally not part of the environmental protection regulations set forth in "" hazardous substances (including toxic, corrosive, flammable or lively chemicals).

除了苯乙烯、BCEA（它们含有浓度很高的易燃性、腐蚀性烯酸）和易燃性溶剂稀释配成的EB/UV上光油之外，EB/UV固化材料一般都不属于环境保护条例中规定的&有害物质&（包括有毒、有腐蚀性、易燃或活泼化学物品）。

The optimal liquefaction conditions of the sawdust in tetralin at syngas atmosphere is 300℃, 2 MPa pressure and reaction time of 30 min with the conversion of 75.1% and the oil yield of 48.4%.

在此条件下优化的液化反应条件为，以四氢萘为溶剂，反应温度为300℃，气体压力为2 MPa，反应时间为30min，转化率为75.1%，液化油收率高达48.4%。

A series of modified polyurethane elastomer materials with different amino siloxane content were synthesized,which were based on polyoxypropylene glycol,aminoethyl aminopropyl poly,toluene diisocyanate and the curing agent dimethylsulfide toluylenediamine.

以聚氧化丙烯二醇或聚氧化丙烯三醇、氨乙基氨丙基聚二甲基硅氧烷、甲苯二异氰酸酯为原料在无溶剂条件下制备预聚体，利用二甲基硫甲苯二胺为固化剂合成一系列氨基硅油改性聚氨酯弹性体材料，并对材料的力学性能、耐热性、表面水接触角等性能进行了测试。
