Diethylamine reacted with benzaldehyde forms benzylidene bis-diethylamine, which, on treatment with carbon disulphide in the presence of moisture, forms diethylammonium diethyldithiocarbamate.ALSO:A compound of an aldehyde, other than formaldehyde, and a secondary amine is incorporated in a vulcanizable...
NCERT solutions for CBSE and other state boards is a key requirement for students. Doubtnut helps with homework, doubts and solutions to all the questions. It has helped students get under AIR 100 in NEET & IIT JEE. Get PDF and video solutions of IIT-JEE Mains & Advanced previous year pap...
[1]Sieves are mildly basic, which triggers aldol reactions in acetone and can decompose some compounds. For example, after prolonged storage (8-10 months) of triethylamine over 3A sieves I’ve noticed a yellow discolouration in the solvent, likely due to formation of diethylamine. ...
The invention consists in the manufacture of new substituted pyridine-ortho-dicarboxylic acid diamides by reaction of a pyridine-ortho-dicarboxylic acid or a derivative thereof, such as for instance a salt, an ester, a halide or an anhydride, on a primary or secondary aliphatic amine or a salt...
Why is Iodine (I_2) considered a good contrast agent? Why is lidocaine a better nucleophile than diethylamine? Why is 1-propanol soluble in water but ethanethiol and chloroethane are not? Why do secondary halides only react (with sodium iodide in acetone and sodium...
1. Understanding the Lucas Test: The Lucas test is a qualitative test used to differentiate between primary, secondary, and tertiary alcohols based on their reactivity with Lucas reagent, which is a mixture of concentrated hydrochloric acid (HCl) and anhydrous zinc chloride (ZnCl2). 2. Reactivity...
Which reactant in the following pairs is more nucleophilic? {eq}\displaystyle \rm -NH_2 {/eq} or {eq}\displaystyle \rm NH_3 {/eq} Nucleophile A nucleophile is a substance with high electron density and is able to donate some of these electrons to electron-poor substances. From...
Diethylamine hydrochloride (0.122 g; 5.0 mmol) was added and the reaction mixture was heated for ten minutes at 100° C. in a sealed vial in a microwave synthesiser. DMF was removed in vacuo and the residue was partitioned between ethyl acetate (30 ml) and water (30 ml). The phases ...
Nitrosamine and propene were detected for the reactions of diethylamine and isopropylamine, showing differential mechanisms between primary and secondary alkylamines. Finally, mechanistic analysis using ab-initio methods was performed and compared with the molecular mechanism proposed for the decomposition of...
The secondary amines used for forming the thiocarbamate may be morpholine, piperidine dimethylamine, hexamethyleneimine, dibenzylamine, methylcyclohexylamine, dibutyl amine, diamylamine, dipropylamine, diethylamine and diphenylamine. The primary amines for reaction with the thiocarbamate may be n-butyl, n-...
