An excellent EL device having low driving voltage, high luminous efficiency and long life can be obtained by using a charge-transporting thin film composed of a charge-transporting varnish which contains an arylsulfonic acid compound represented by the formula (1) or (2) below as an electron-acceptor material especially in an OLED device or a PLED device.[In the formulae, X represents O, S or NH; A represents a naphthalene ring or anthracene ring having a substituent other than X and n SO3H groups; B represents a substituted or unsubstituted hydrocarbon group, 1,3,5-triazine group or a substituted of unsubstituted group represented by the following formula (3) or (4):(wherein W1 and W2 each independently represents O, S, an S(O) group, an S(O2) group, or a substituted or unsubstituted N, Si, P or P(O) group); n indicates the number of sulfonic acid groups bonded to A which is an integer satisfying 1≦n≦4; q indicates the number of B—X bonds which is an integer satisfying 1≦q; and r indicates the number of recurring units which is an integer satisfying 1≦r.].

An organic acid composition for use in oil industry activities, said composition comprising an arylsulfonic acid in water as well as the use of said composition to perform various operations in the oil industry. There is also disclosed a solid acid composition comprising a corrosion inhibitor ready for dissolution and use.

The present invention relates to preparation process of hydrothermally catalytic cracking viscosity reducer containing amphiphilic structure for thick oil exploitation. The preparation process includes the following steps: 1. preparing material arylsulfonic acid in 19-21 weigh portions, and iron oxide powder in 1.8 or 1.2 weigh portions; and 2. reaction between arylsulfonic acid and iron oxide powder at 80-160 deg.c for 1-3 hr, dissolving the resultant with acetone in 0.9-1.3 times arylsulfonic acid weight, filtering and stoving the filtrate in a stove at 50-80 deg.c to obtain the brown ropy liquid viscosity reducer. The present invention has the features of low cost, high universality and good low temperature viscosity reducing effect.
