摘要:
<正>用气相色谱一质谱联用(GC-MS)分析了一步法松油醇生产中副产物的化学组成,共鉴定出22个化学成分,主要成分有宁烯、异松油烯、α-蒎烯和1,8-桉叶素等。研究了松油醇生产中副产物在SO42-/TiO2-ZrO2型固体超强酸催化剂作用下的反应规律,分析了催化剂的焙烧温度、反应温度、反应时间及催化剂用量等因素对其催化性能的影响。考察了催化剂放置时间对异构产物的影响和催化剂重复使用情况。结果表明,该催化剂对松油醇副产物的反应有较高的催化活性。通过GC-MS分析,其主产物为对伞花烃,副产物主要是异松油烯和α-松油烯。适宜的催化剂制备条件是:M(钛):M(锆)=3:1,650%:焙烧温度。在此制备条件下松油醇生产中副产物反应的适宜工艺条件为:反应时间6h、反应温度130cc、催化剂用量3%。所得产物中对伞花烃含量为60.60%。
Abstract:
In this paper forests on water conservation, the litter amount and the water holding characteristic under three stand ages were studied. The results showed that the order of litter amount was near mature forest>haft-aged forest>young forest, and the litter amount of each stand age was 32.20,30.59,22.27 t/hm2 respectively. The water-holding capacity of litters was obviously different in the different types of litters of the same stand. The orders were broadleaves, needles, fruits, branches, barks. The water absorption speed of the litter decreased with immerse time increasing. The fast speed in 0-30 min. The relationship between the water absorption speed of the litter and the immerse time was analyzed by SPSS 13.0. The equation was S=ktn. The maximum water-holding capacity increased with the increase of stand ages. It was 53.28 t/hm2 in young forest,71.91 t/hm2 in half-aged forest,77.49 t/hm2 in near-mature forest,with the equivalent water depth 5.33,7. 19, 7.75 ram, respectively.
