98-69-1 Usage

Uses

4-Ethylbenzenesulfonic acid was used to dope high conducting polypyrrole thin films.

Check Digit Verification of cas no

The CAS Registry Mumber 98-69-1 includes 5 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 2 digits, 9 and 8 respectively; the second part has 2 digits, 6 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 98-69:
(4*9)+(3*8)+(2*6)+(1*9)=81
81 % 10 = 1
So 98-69-1 is a valid CAS Registry Number.

Smectic liquid crystals from supramolecular guanidinium alkylbenzenesulfonates

Mathevet, Fabrice,Masson, Patrick,Nicoud, Jean-Francois,Skoulios, Antoine

, p. 2248 - 2254 (2007/10/03)

A homologous series of guanidinium alkylbenzenesulfonates from ethyl to tetradecyl were synthesized and characterised. Their thermotropic polymorphism was investigated by polarizing optical microscopy, differential scanning calorimetry, and dilatometry. The structure of the smectic liquid crystal phases obtained at high temperature with the compounds from octyl to tetradecyl was analysed by X-ray diffraction. The supramolecular assembling of the ionic species inside the smectic layers was investigated by infrared spectroscopy.

Mass Spectral Studies of Alkylbenzenesulphonic Acids Through Their S-Benzylisothiouronium Salts

Borthakur, Arun,Rao, V. S. Bhaskar

, p. 48 - 54 (2007/10/02)

The mass spectra of alkylbenzenesulphonic acids in the form of their S-benzylisothiouronium salts have been studied.These S-benzylisothiouronium salts dissociated into two parent reactant ions: (i) alkylbenzenesulphonic acid and (ii) S-benzylisothiourea.The characteristic fragmentation patterns of alkylbenzenesulphonic acids (0-5 substituted alkyls) were studied and compared with those of the parent ion peak hydrocarbons.The intensity of the molecular decreased with the increase in the molecular weight of the sulphonic acids.Desulphonation as well as loss of the alkyl group was observed in all the spectra.Migration of the alkyl group from S to 0, followed by degradation, was also observed in all the spectra studied.
