Inclusion ratio of β cyclodextrin to dibenzoy peroxide and benzoic acid is obtained with spectrophotometry.The mechanism of the inclusion was studied,too. The results showed that β-CD react with dibenzoyl peroxide to form a 1:1 or 2:1 host-guest complex, with the apparent formation constants of 5.0× 10~2and 2.5× 10~4 , respectively.β-CD reacts with benzoic acid to form a 1:1 host-guest complex with the apparent formation constant of 6.9 × 10~2 after the dibenzoyl peroxide was reduced by hydroxyl ammonium chloride.

The results show that:First, concentration of hydrogen peroxide have the most obvious influence to oil yield and carbon black yield,with the increase of concentration of hydrogen peroxide the oil yield first increase then decrease,when concentration of hydrogen peroxide is 8.19% or so,the oil yield reach to the biggest value, and with the increase of concentration of hydrogen peroxide carbon black yield decrese;Then,reaction time have more obvious influence to oil yield and carbon black yield,oil yield increase but carbon black yield decrease with the increase of reaction time;Thirdly,reaction tempreture have some influence to oil yield and carbon black yield,samely,oil yield increase but carbon black yield decrease with the increase of reaction tempreture;Finally,reaction pressure does almost no influence on oil yield and carbon black yield.

研究结果表明：过氧化氢质量浓度对产油率和炭黑产率的影响最为显著，产油率随过氧化氢质量浓度的提高先提高后降低，在过氧化氢质量浓度为8.19%左右时达到最大值，炭黑产率随过氧化氢质量浓度的提高而降低；反应时间对产油率和炭黑产率的影响也比较显著，产油率随反应时间的增加而提高，炭黑产率随反应时间的增加而降低；反应温度对产油率和炭黑产率也有一定的影响，产油率随反应温度的提高而相应地提高，炭黑产率随反应温度的提高而降低；在本文实验范围内，反应压力对产油率和炭黑产率基本上没有影响。

Producing high purity chlorine dioxide by hydrogen peroxide method,several stabilize which can reduce the decomposition of hydrogen peroxide were studied DTPMP、PBTCA、HEDP are certained as the ideal stabilizer and the optimum amount of these three stabilizer are 0.6%,1.0%,0.6% of hydrogen peroxide amount respectively.

摘 要：采用过氧化氢法制备高纯度二氧化氯，研究了几种抑制过氧化氢分解的稳定剂。确定了DTPMP、PBTCA、HEDP三种稳定剂效果较理想，其最佳用量分别为反应液中过氧化氢质量分数的0.6%、1.0%、0.6%。

Because the affair is actually very serious, we might as well take in to analyze once;Need not to doubt first, health department and three deer companies all have already publicly admitted at least 700 ton baby's kid's milk powders be subjected to three chlorine cyanotype An pollution, have already found out an in a short time number as well, the province appears numerous babies and kids in the meantime, the Bi urine system stone calculus really is because ate a milk powder in of three chlorine cyanotype An result in, so we will ask, three deer companies admit of just have 700 ton milk powders to be subjected to three chlorine cyanotype An pollution, talk the idea of bottom may be an emergence surprised in the production of circumstance, be also say that not and intentionally add of three chlorine cyanotypes the An be this kind of chemistry product, let the public produce a kind of imagination, perhaps just individual case, the Zhao returns to product behind again check pure pollution the reason can resolve a problem, after all this be a Zhao the race brand of, it is all to be loudly appealing and protecting race brand now?

由于事情实际上很严重，我们不妨加以分析一下；首先，毋庸置疑，卫生部和三鹿公司都已经公开承认至少有700吨婴幼儿奶粉受到三氯氰胺污染，也已经查明短时间内数省同时有众多婴幼儿出现泌尿系统结石确实是因为食用了奶粉中的三氯氰胺所造成，那么我们就要问了，三鹿公司承认的只是有700吨奶粉受到了三氯氰胺污染，言下之意可能是生产中出现意外的情况，也就是说并非故意添加的三氯氰胺这种化学制剂，让公众产生一种想象，也许只是个案，召回产品后再查清污染原因就可以解决问题了，毕竟这是一个著名的民族品牌，现在不是都在大声呼吁要保护民族品牌吗？

In this paper, firstly, a detail analysis、 study and discussion of the existing disposing-chlorine method were made, on this condition, a new method based on the way of oxidation and deoxidization was discussed, phosphoramidic acid chelate resin and DOOl cation exchange resin were chosen as framework materials, two kinds of new disposing-chlorine materials could be obtained by loading Fe~(2+) on the skeleton of the materials, the surplus residual chlorine was disposed by taking advantage of chlorine oxidizing Fe~(2+).
