摘要： NITROGEN-HETEROCYCLIC PHOSPHONATES WHEREIN THE PHOSPHONATE GROUP IS OTHO- OR PARA- TO THE NITROGEN HETEROCYCLIC GROUP, WHERE THE COMPOUNDS ARE CHARACTERIZED AS FOLLOWS:

((-)O)2-P(=O)-C
WHEREIN THE DOTTED LINE REPRESENTS A CYCLIC STRUCTURE WHICH CYCLIC STRUCTURE MAY BE THE SOLE CYCLIC STRUCTURE, OR MAY BE ATTACHED TO OTHER CYCLIC GROUPS. THESE NITROGEN HETEROCYCLIC PHOSPHONATES ARE PREPARED BY REACTING AN AROMATIC NITROGEN HETEROCYCLIC COMPOUND, WHEREIN THE NITROGEN ATOM IS IN THE FORM OF A SALT OR A QUATERNARY, WITH A PHOSPHITE SALT, PREFERABLY IN THE FORM OF ESTERS OF THE PHOSPHITE AS EXEMPLIFIED BY THE FOLLOWING EQUATION:

R''-(+)N (R-O)2-P(=O)-

C
THESE COMPOUNDS WHICH MAY BE CHARACTERIZED AS PHOSPHONATES OF DIHYDROAROMATIC NITROGEN HETEROCYCLES HAVE MANY USES INCLUDING THEIR USE AS BIOCIDES SUCH AS BACTERIOCIDES, HERBICIDES, CORROSION INHIBITORS, CHELATING AGENTS, ETC.

摘要： The seal is formed by two engaging surfaces of a sealing disc and the valve housing. The disc consists of PTFE and has numerous concentric micro-grooves, which correspond with grooves in the sealing surface of the valve housing, this surface being of a metallic material. Alternatively, the sealing disc may be cone-shaped so that the closing of the seal, the external sealing surface is the first to engage on the level sealing surface of the valve housing.

摘要： WHERE AT LEAST ONE OF THE R''s, which may or may not be the same, is a substituted group, for example alkyl, aryl, cycloalkyl, alkaryl, aralkyl, etc. and derivatives thereof. An example of a compound which is not itself a guanidine type compound but is capable of forming a guanidine-type compound is cyanamide NH2CN which reacts with itself to form dicyandiamide.

RESIDUE AND MAY BE ILLUSTRATED BY THE FOLLOWING:

The use as a water clarifier of the compounds formed by reacting guanidine-type compounds with polyamines. The compounds are formed by the reaction of guanidine-type compounds, (including compounds which although not guanidine-type compounds are capable of forming guanidine-type compounds). In general, guanidine-type compounds are those which contain the
