The feldspars of topaz-lepidolite granite in Yashan late stage are P-rich albite and Kfeldspar, and the phosphorus goes into feldspar structure in the form of PAlSi〓 substitution. The phosphorus contents of feldspars vary according to their crystal habitus. In general, the feldspars of later generation have the higher average phosphorus content than that of earlier generation, and the albite contains higher phosphorus than the K-feldspar in the same generation. The zircon is highly rich in Hf, U, P and Al. The phosphorus enters the zircon structure mainly by the form of〓P〓〓Si〓, Al〓P〓Si〓 or P〓Al〓Si〓, Zr〓 substitution. The P-rich zircon is the production of the highly evolved magma, and it might be one of the important characteristic minerals of the high-P subtype granite. The manganocolumbite, manganotantalite, wodginite and titanowodginite are the main niobium and tantalum minerals.

In the contaminated lard sample, 6 organic compounds have been thus identified to be the raw materials or byproducts in the production of organic tin compounds. Based on the identified contaminants, it can be postulated that the chemical structure of the organic tin compound is dibutyltin-bis-(2-isooctyl thioacetate). The method is simple and precise, and has not been reported in the local literature.Keywords Organic tin compound, Lard, SPME-GC-MS
经过摸索研究,采用固相微萃取方法富集挥发性杂质,直接注入色谱中,经色谱分离,质谱测定,确定了杂质的结构,由杂质成分推断生产有机锡所用的原料,然后判断合成路线,最后确定有机锡的结构,从有毒猪油中鉴定出2-巯基醋酸异辛酯、双(2-醋酸异辛酯)二硫、双醋酸异辛酯硫醚等6种与有机锡有关的杂质,并与相应的有机锡工业品对照,发现工业品中也含有这些杂质,与其合成过程的原料及副产物相符,从而确定有机锡化合物为二硫代醋酸异辛酯二丁基锡。
