(1) Euonymus geometer, Abraxas miranda (Butler), is one of the principal garden pests inShanghai, infesting, in particular, Euonymus japonicus Thumb and E. Fortunei Hand-Mazz.,Celastraceae. In China, its distribution includes the provinces of Kiangsu, Chekiang and Kwei-chow as well as some northeastern provinces. (2) Investigations in Shanghai reveal that three generation of euonymus geometer occur inthe course of a year, with the pupa surviving the winter underground. Adults of the first genera-tion start emerging in the first half of April and the larvae of third generation go undergroundto enter into pupa stage in the middle of November. During this period the larvae infest theleaves of Euonymus japonicus Thumb and E. Fortunei Hand-Mazz. (3) This report deals with the life cycle and habits of this pest. It also includes data rela-tive to the horizontal and vertical distribution densities of its winter pupa. The horizontal dis-tribution density is highest in places just under the plant-stems, reaching 37.8-53.3%, while inplaces about 1 ft beyond the stems, no pupa is to be found. Its vertical distribution density ishighest in places 2 mm from the ground surface, ranging from 37.5% to 45.1%, while below5 mm no pupa has been found. (4) Chemical control experiments have been carried out in the laboratories. The results ofthese experiments show: (a) 10% DDT powder is fully capable of exterminating larvae of all stages; (b) 5% DDT powder registers 95% mortality when treated against olders larvae; (c) 1/1000 dipterex solution registers 97.5% mortality when treated against the larvae of laterstages; (d) 1/2500 dipterex solution registers 100% mortality when treated against larvae of 2-3stages; 78.4% against larvae of later stages; (e) 1/150, 1/200 and 1/300 solution of lead arsenate effects only low mortality. On the basis of the data on the horizontal and versical distribution densities of the over-wintering pupa as reported here, it is recommended that steps should be taken to unearth andesterminate the winter pupa in combination with the anti-four-pests campaign in the winter. Inview of the poor flying ability of the adult, it is also recommended that survey should be madeto ascertain the growth data of the adults of the first generation and exterminate them whenthey start emerging. The survey should be made on basis of past records and the weather condi-tion of the current year.

The type of Hei-Shan bentonite (Liaonin Province) was determined by the use of component analysis, thermal analysis and X-ray diffraction analysis. The results show that the bentonite is of calciumS type. By_treating with sodium chloride solution to convert the calcium bentonite into sodium bentonite, cation exchange with an aliphatic quarternary ammonium salt in aqueous solution was carried out.

The type of Hei-Shan bentonite (Liaonin Province) was determined by the use of component analysis, thermal analysis and X-ray diffraction analysis. The results show that the bentonite is of calciumS type. By_treating with sodium chloride solution to convert the calcium bentonite into sodium bentonite, cation exchange with an aliphatic quarternary ammonium salt in aqueous solution was carried out. The quarternary amrhonium salt is triethyl hexadecyl ammonium chloride, which was prepared by first converting cetyl alcohol into cetyl chloride followed bythe reaction with triethylamine. The aminated bentonite was then dispersed in mineral oil to form a structural dispersion system, while small amount of butyl alcohol was added as a dispersing aid. The structural system was evaluated as a lubricating grease. The thickening ability of the said aminated bentonite was moderate, however, the said system satisfied the requirements as a lubricating grease.

Sulfonated coal possesses very good adsorption action for phenols and its homologues. The experiment mentioned here systematically investigated the adsorption rates, the equillibrium concentrations and the factors affecting the adsorption action of the sulfonated coal for phenolic compounds. The results obtained show that the adsorption rates of sulfonated coal for phenolic compounds are very rapid and the equillibrium reached after 90 minutes. Among the homologues, the adsorption of phenol is preferential. The experiment proves that the adsorption is substantially the action of the active center of sulfonated coal upon the hydroxyl group on the aromatic rings. Applying the above conclusions, the approximate total quantity of phenolic compounds adsorbed on sulfonated coal may be obtained when various samples of waste water of different phenolic compound content are treated with sulfonated coal. In case the operation temperature is raised to 70℃, the adsorption concentration decreases apparently, but low temperature (<10℃)is also disadvantageous. Generally, temperature in the range 20-30℃ is favorable. It is obvious that high temperature favors the desorption of phenolic compounds from sulfonated coal. When the pH value of the solution gets above 8, the adsorption of phenolic compounds on sulfonated coal decreases apparently, a sharp drop being observed. The presence of sulfides in solution weakens the adsorption of phenolic compounds on sulfonated coal on account of the formation of phenolates. Other impurities such as amino- and cyano- compounds as well as organic acids do not show apparent influence, if their concentration is not higher then their usual content in waste water. Excessive alkali in solution apparently suppresses the adsorption ability of sulfonated coal for phenolic compounds, and even blocks up the action entirely. In short, either in view of the adsorption rate or the factors affecting the adsorption process, the facts obtained prove that the dephenoling action of sulfonated coal is an adsorption rather than an ion-exchange process.

磺化煤能够有效的脱除煤焦油污水中的酚类,以前的试验对磺化煤的脱酚效果,使用寿命和再生条件等进行了一系列的考察,证明它是一个简易可行的方法,并初步拟定了一个利用磺化煤脱除煤焦油污水中酚的工艺流程。 在此基础上,又对磺化煤吸附酚类的速度,操作平衡吸附量,及影响吸附过程的因素等,进行了较为详细的考察,为今后进一步的深入研究和发展,提供了新的线索和理论根据。试验结果多方面肯定了磺化煤脱酚是吸附过程。
