Description

PREPARATION OF THE FORMULATIONS

Preparation of the Formulation

[0326] According to the ratios and components as specified in Table 2, all components were mixed, and the resulting mixture was stirred until complete dissolution of the solid and analyzed for the content of NBPT, NPPT, NxPT (by HPLC), viscosity, dissolution (2%) in water and pH. For example, in case of Ex. #310092, the technical mixture LT (25% pure NxPT) was mixed with 50.08% benzyl alcohole and 10% LFG, 10% DML and 0.25% colo. The mixture was stirred until complete dissolution of the solid and analyzed for NxPT content (by HPLC), viscosity, dissolution (2%) in water and pH.

Formulation Storage Stability

[0327] The mixture of each example (e.g. Ex. #310092) was stored in closed bottles for 14 days at 54? C. (referred to as heat stability test in the following) and then analyzed for the content of NxPT. The mixture of each example (e.g. Ex. #310092) was also stored in closed bottles for 14 days at 5? C. (referred to as cold stability test in the following) and then analyzed for the content of NxPT. The storage stability in % was calculated as difference between the content in the heat stability test and the content in the cold stability test.

Coating of Urea

Example 1.1

[0328] 500 g granulated urea was charged to a rotating drum (Type Hege 11) and 2 g of the formulation of each example (e.g. Ex. #310092) was sprayed on the urea using a rotating disc. The homogeneous coated urea was discharged after 1 min and analyzed for the content of NBPT, NPPT, NxPT (by HPLC).

Stability on Urea

[0329] The coated urea sample of 300 g was stored in a petri dish for 4 weeks at 50% humidity in a climate chamber. For analysis the sample was homogenized and analyzed for the content of NBPT, NPPT, NxPT (by HPLC)

[0330] The content of NxPT measured by HPLC measurement is always the sum of the both components NBPT and NBPT.

[0331] Viscosity was measured at the undiluted formulation with a cone-plate rheometer AR 2000ex (TA Instruments) at shear rate of 100s.sup.?1 and 20? C.

[0332] The pH value was measured at 2% concentration in CIPAC water D.

[0333] All examples of the inventions are liquid, clear compositions which are either colourless or yellow.
