Unsymmetrically substituted dicarboxylic acid diamido ammonium salts and their use for gas hydrate anti-agglomeration
The instant invention concerns a gas hydrate inhibitor comprising an N alkyl N′ (N″,N″-dialkylammoniumalkyl)dicarboxylic acid diamide salt represented by the formula (I) ##STR00001##
wherein R is an alkyl or alkenyl group having from 8 to 22 carbon atoms, R.sup.1 is hydrogen, a C.sub.1- to C.sub.22 alkyl group or a C.sub.3- to C.sub.22 alkenyl group, R.sup.2 and R.sup.3 are each independently an alkyl group containing 1 to 10 carbon atoms or together form an optionally substituted ring having 5 to 10 ring atoms, wherein the ring may carry up to 3 substituents, R4 is hydrogen, A is an optionally substituted hydrocarbyl group containing from 1 to 18 carbon atoms, B is an alkylene group having from 2 to 6 carbon atoms, Y is NR.sup.5, R.sup.5 is hydrogen, a C.sub.1- to C.sub.22 alkyl group or a C.sub.3- to C.sub.22 alkenyl group, and M− is an anion,
a process for producing a compound according to formula (I), the use of an N alkyl N′—(N″,N″-dialkylammoniumalkyl)dicarboxylic acid diamide salt of the formula (I) as an anti-agglomerant for gas hydrates, and a method for inhibiting the agglomeration of gas hydrates which comprises the addition of an N alkyl N′ (N″,N″dialkylammmoniumalkyl)dicarboxylic acid diamide salt of the formula (I) to a fluid containing gas and water.
Composite Form of Tetraacetylenediamine

Compounds and methods for use in detecting gabapentin
Compounds and methods for use in detecting gabapentin in a sample suspected of containing gabapentin are disclosed. Gabapentin derivatives are used to produce gabapentin conjugates. A gabapentin-immunogenic carrier conjugate may be used as an immunogen for the preparation of an anti-gabapentin antibody. A gabapentin-detectable label may be used in a signal producing system in gabapentin assays.

Ethyl Benzyl Quaternary Amines of Amido Amines for Improved Antifungal properties
Ethyl benzyl quaternaries having superior anti-fungal properties versus their benzyl quaternary analogs. The ethylbenzyl amidoamine quaternaries of the present invention are easily produced without significant waste and with minimal capital, while possessing improved antimicrobial properties. These molecules are useful in a range of applications such as fungicides, personal care as treatments for acne, dandruff, psoriasis and other fungal skin born conditions, as well as in feminine products where an antifungal is required that is gentle on the sensitive tissues, as well as HIV prevention. These molecules are also excellent hair conditioners and laundry fabric softeners.
