The reaction of indophenols with benzoyl peroxide to form indophenoxy radicals was of the first order with respect to indophenol. The annihilation of indophenoxy radi- cals in benzene was a second-order reaction with respect to the radical. From the values of rate constants of the annihilation of radicals having different substituents data were obtained on their stability. This stability dropped sharply on going from radicals with o-tert-alkyl substituents to radicals with less-bran&hed groups. Orig. art.* has,1 7 figures and 2 tables.

TITLE: On Methods of Corrosion Testing of Welded Joints of Aluminum in Nitric Acid PERIODICAL: Avtomaticheskaya svarka, 1959, Nr 8, pp 49-56 (USSR) ABSTRACT: The article deals with methods of testing corrosion resistance of welded joints of aluminum. The authors wish to ascertain the character of the action of nitric acid in relation'to its concentration and temperature, and more precisely define the necessary preparation of surface of samples and other experimental conditions in order to work out the most acceptable accelerated method of testing welded joints of aluminum in nitric acid. The authors open with a review and critique of other work in this field, including that of V.P. Ba- trakov ZR-ef ~7, V.A. Savchenko ZR-ef 77, and F.B. Slo- myanskaya and A.N. Krutikov Ref lg-, but they find a comparison difficult because the methods used varied. Card 1/4 A method of testing welded joints of aluminum, worked SOV/125-59-8-6/18 On Methods of Corrosion Testing of Welded Joints of Aluminum in Nitric Acid out by NIIKhR4RSh - boiling test samples in concentrat- ed nitric acid for a long period of time (100-200 hrs)- is criticized as having poor reproducibility of re- sults. The experiments described in this article were performed on type Al aluminum of the following compo- sition: 0.20% Fe, 0.20% Si,.4,;0.01% Cu, the rest - aluminum. Sample dimensions were 70x3Ox4 mm; seam width was 12-14 mm. Nitric acid in concentrations of 10, 20, 30, 40, 50, 60, 70, 80% by wt. were used. Fur- ther particulars are contained in the text. The fol- lowing conclusions were reached on the basis of the experiments: 1) the highest rate of corrosion was attained using 30% HNO - for accelerated corrosion testing it is recommenh9d that boiling 50% HNO be used; 2) corrosion speed in 50% HNO was dete?Mined as a function of time (Fig 1); the hrve of this func- tion levels out 2 hours after the start of the test; 3) tests in 50% HNO guarantee a higher reproducibility Card 2/4 of results in compa?ison with tests in concentrated SOV/125-59-8-6/18 On Methods of Corrosion Testing of Welded Joints of Aluminum in Nitric Acid acid; in addition the character of the corrosion da- mage is preserved. The condition of the surface of the samples was found to have a comparatively small effect on the rate of corrosion (Fig 3). Further tests were carried out for comparative evaluation of the corrosion resistance of welded joints- a) boiling samples in 98% HNO , for 100 hours, and b~ by the ac- celerated method, i.e. two-hour boiling in 50% HNO . Samples with three types of welds were used. SampKs were compared by weight in arriving at a criterion for corrosion resistance. Results are tabulated (Table 3). Results of the 100-hour test in 98.3% HNO support known data to the effect that identical sample; in the same acid and under similar testing conditions give poorly corresponding results. However, good reproduc- ibility of results was obtained in the 2-hour tests with 50% HNO In addition, structure and defects in the seam sh8w* up better after the two-hour test.

TITLE: On the Problems of Accelerated Corrosion Tests of Welded Aluminum Joints in Nitric Acid PERIODICAL: Avtomaticheakaya svarka, 1960, Nr 1, pp ?4-?8 (USSR) ABSTRACT: In their previous work ZR-e� g the authors showed that 50016 nitric acid can be used for the accelerated testing of aluminum welds for corrosion resistance. Boiling for two hours in such an acid concentration ensures better results thap:tests with concentrated nitric acid. The optimum sizes of test samples are determined and the accelerated test method is explained. The size of the samples can considerably influence the results of the tests. Table 1 and graphs 1 and 2 show test results de- pending on the size of samples. The latter were tested for two hours in boiling 50% nitric acid. Figure 3 shows samples of different length after the tests. Card 1/3 As the ratio of the area of the basic metal in the SOV/125-60-1-10/18 On the Problems of Accelerated Corrosion Tests of Welded Alumin- um Joints in Nitric Acid sample increases in relation to that of the weld, the mean rate of corrosive destruction gradually drops. To determine the influence of the size of the butt end sur- faces on corrosion of the welded joint, different thick- nesses of the latter were tested. The results o'L these tests are given in table 2. Experiments were made by putting samples straight into boiling acid, and by putt- ing them into cold acid and then bringing it up to the boiling point. The average rate of corrosive destruction depending on these two conditions is shown in table 3. On the basis of investigations, the results of which are described in the previous work Z7Ref .17 and in this ar- ticle, and after consideration of the results of tests conducted at plants.,an industrial test method was de- veloped. It includes instructions for the preparation of samples, the tests themselves and the methods of evalua- Card 2/3 ting results. The method has been tried at a number of SOV125-60-1-10/18 On the Problems of Accelerated Corrosign Tests of Welded Alumin- um Joints in Ntric Acid plants where it received approval. It can be used for testing the welded parts'of chemical equipment for corrosion by nitric acid. The authors thank eng~heer Ivleva (Penzkhimmash), S.V.

One of tbB most efficient methods applied for this purpose is the mchvzdcal cleanIn of pipes vith scrapers attached to a rotating roa. Most oilfields employ scrapers vith rotating blades.

This scraper can be employed without rotating the rod to vhich it is attached.
