(TEA)存在下开环生成苯磺酸。很简单的一步。但问题是Sigma只能买到90%的technical
grade，结果溶到THF（freshly distilled）后，加入TEA（freshly distilled）
后就马上出现很多白色固体，估计就是不纯的东西比如苯磺酸之类跟TEA生成盐。怎么提纯一
下这个commercial的2-Sulfobenzoic acid cyclic anhydride？我不是有机的，
不过实验室基本反应条件还是有的。
或者谁知道哪里能买到高纯度的2-Sulfobenzoic acid cyclic anhydride?

经济衰退已经过去.经济复苏的程度在未来一两年还是未知数
但是下半年肯定有很多跟经济挂勾的行业要报告复苏的迹象.
譬如汽车.
大盘很多基金怕落后正在逢低吸进, 钢铁和其他cyclicals应该可以维持强势到九月.

SP500 Rally Nearing A Cyclical High

SP 500 may be nearing a cyclical high in the coming two weeks of trade:

THe SP 500 has rallied to a post June 4th high of 1409 this week, about 13

The average length of the previous 3 Secular Bear Markets was 18 years with
a minimum of 16 years and a maximum of 21 years. Thus if you add 18 years
to the year 2000 and take + or - 3 years on either side then the next
Secular Bull Market may not begin until sometime in the 2015 to 2021 time

不过diamine里面有个酸敏感的集团
所以几次反应都得不到产物，复反应很多。

请问cylic imide合成有什么好的review可以看么？
diamine 和 maleic anhydride的开环反应应该室温就可以进行
但在脱水闭环时，因为酸敏感，NaOAc可能不能用，除了NaOAc还有什么常用的脱水剂么？

If the unemployment situation in this country were a cyclical issue (which

发帖数: 8565 | 14 我们证明一下|H|=n.
根据fundamental theorem of finite abelian group，一个finite abelian group可
以表示成cyclic group的直积。这就相当于一个向量空间可以分解成几个一维空间一样
，每个一维相当于一个坐标维，空间中的每个元素都能分解成坐标维元素的线性组合，
可以写出其坐标。
选定每一个cyclic group中的generator，这种选定方法不是唯一的，但是可以选定。G
到Z_n的一个homomorphism相当于给每个generator元素赋值，反之亦然，给每一个
generator的任意一套赋值都能延伸成一个homomorphism。所以H的cardinality就等于
给每一个generator赋值的方法的数目。
看一个直积component，也就是一个cyclic group，假设它的order为m，那么它的
generator的order也为m，Z_n中有唯一一个order m的子群，给cyclic group
generator赋值只能选遍这个order m的子群，有m种方法。
所以总的赋值方法数... 阅读全帖 |

发帖数: 3281 | 22 我觉得低P/E是不适合做为选cyclicals的标准. e.g. shipping
大多数cyclicals是很多analysts cover的领域. 我们一般的野鸡FA是不可能比他们对
这个industry 的supply and demand 的了解更趋前的. 我们也是看BDI,看了他们的分
析才知道趋势.
如果你看drys, 和其他shipping stocks,甚至其他cyclicals的p/e, 开始上升的一大波
那时候p/e都不是低的. 有些还是negative的.那是因为industry的专家已经看见了spot
rate的增加, 也已经知道supply and demand的不平衡了. 所以愿意给它high
multiples.
等到p/e开始缩小, 这时候很多人都已经发觉了, 因为earnings开始显现出来了.
所以说p/e小, 不一定是说它便宜, 而是earnings 已经catch up with expectation 了
.
当然shipping analysts也承认这次他们underestimate了趋势. 可是他们其实还是比大

他的TANGO作品有很多，我最喜欢的就是他在晚年自己做曲。并且参加演奏的这张＂THE
ROUGHT DANCER AND THE CYCLICAL NIGHT＂。这是１９８７年他在纽约录音的，也算
是他对乐迷的最后一次谢幕作品。
整张碟的气氛是非常黑色的，这些乐曲的节奏时快时慢，有的时候非常幽怨，有的时候
如同酒醉了在回想当年。PIAZOLLA把自己所有知道的JAZZ和TANGO在这个作品里面完全

this cyclical bull market since March 2009 has been grinding higher
after a strong initial surge.
most bull markets in the past did not end in the grinding phase
instead, they ended with a parabolic spike
a good example is Nasdaq in 2000

为表示诚意，我汇总sector day-to-day涨幅如图。注：3/18日的数据丢失了，是根据
GOOG数据近似算的。
大致而言,周五收盘与上周五收盘对比，
Basic Materials 小跌
Capital Goods 小涨
Conglomerates 大涨
Cons. Cyclical 大涨
Cons. Non-Cyclical 小涨
Energy 中跌
Financial 小涨
Healthcare 中涨
Services 小涨
Technology 小涨
Transportation 中涨
Utilities 平
问题比较严重的是能源。周五所有板块普跌，显示资金全 |

这次主要是technology/consumer non-cyclical/consumer cyclical/capital goods
看看那些retail/food/restaurant都涨了多少啊。。。
材料都不是很强，utility很弱，能源最烂。 |
