powers of breaking, are constituted of 32...57% by weight of resin on the basis of aducti you vegetable oils with altered anhidrina maleica with resin with a high content of fenolica groups hidroxilice,neutralized with ammonia or ammonia mixture trietilamina - diethylamine, as a binder, ...
pressure. The colorless crystals are freely soluble in water and in most organic solvents, with the exception of petroleum ether. The same compound can for example also be ;0 obtained by the action of pyridine-2:3-dicarboxylic acid-dichloride on an aqueous diethylamine solution. In analogous...
II. Diethylamine. III. Trimethylamine. A) I and II only. B) II and III only. C) I and III only. D) I, II, and III. Find the Grignard reagent and what carbonyl compound might you start with to prepare the given alcohol. Which is less soluble in water? 1-pentanol ...
Recent reports suggest that vitamin B1 (thiamine) participates in the processes underlying plant adaptations to certain types of abiotic and biotic stress, mainly oxidative stress. Most of the genes coding for enzymes involved in thiamine biosynthesis in Arabidopsis thaliana have been identified. In our...
Columns were sequentially washed with 30 volumes lysis buffer, 20 volumes 10 mM Tris 0.5% triton X-100 300 mM NaCl pH 8, 20 volumes 10 mM sodium phosphate 0.5% triton X-100 450 mM NaCl pH 10, and eluted with 0.05 M diethylamine 0.5% triton X-100 650 mM NaCl pH 11.5. 1.5 mL ...
0.2 mL of diethylamine was slowly added dropwise thereto. After the resulting solution was stirred for 20 hours, the reaction solvent was mixed with Celite and removed by concentration under reduced pressure, and a target compound was purified by column chromatography (EA:Hex=1:1) to obtain 7.6...
titanium dioxide and a water-soluble urea-formaldehyde resin and/or a condensation product of epichlorohydrin and diphenylol propane; and (3) copolymers of styrene, ethyl acrylate and acrylic acid which have been hydroxyethylated with ethylene oxide and neutralized with ammonia, diethylamine, triethylam...
Mention may be made, as secondary amine which can be used to prepare the initiators, of dimethylamine, diethylamine, dipropylamine, di(n-butyl)amine, di(sec-butyl)amine, dipentylamine, dihexylamine, di(n-octyl)amine, di(2-ethylhexyl)amine, dicyclohexylamine, N-methylbenzylamine, diallylamine, ...
The amine is used in a proportion of 2 to 25 per cent. by weight of the dithiocarbamate. In examples, the amine used is diphenylguanidine, symmetrical triphenylguanidine, benzylcyclohexylamine, triethyltrimethylenetriamine, diethylamine, dicyclohexylamine, triethanolamine, tetraethylene pentamine or benzyl...
one radical in which comprises a straight or branched carbon chain of not less than 10 carbon atoms, and also containing where advantageous one or more of the following additional substances, namely, acid, alkali, reducing agent, soluble soap and a sulphonic acid or sulfuric ester as herein def...
