Leigh E. Walker - Macungie PA
Assignee:
Lonza Inc. - Fair Lawn NJ
International Classification:
C09K 300
US Classification:
252384, 428541, 428907, 106 1832
Abstract:
Applicants have discovered that amine oxides enhance the performance of azoles as fungicides and wood preservatives. Also, amine oxides have been found to provide waterproofing properties and enhance the uniform distribution and penetration of azoles into wood substrates. The present invention provides a composition comprising an amine oxide and an azole, such as a 1,2,4-triazole. The composition of the present invention may be incorporated into or be a wood preservative and waterproofing system, or agricultural product. Another embodiment of the present invention is a method for preserving and/or waterproofing a wood substrate by applying the composition to the wood substrate. Yet another embodiment is an article comprising a wood substrate and the composition of the present invention. The invention also provides a method of controlling fungi comprising applying an effective amount of the composition of the present invention to the fungi or the area on which the fungi grow.

Leigh E. Walker - Macungie PA, US
Assignee:
Lonza Inc. - Annandale NJ
International Classification:
C17C 211/00
US Classification:
564282, 564281
Abstract:
This invention provides a method of preparing a quaternary ammonium hydroxide compound having the formula (NRRRR)OH, wherein Rand Rare independently C–Calkyl; Ris benzyl or a C–Calkyl or a C–Caryl-sutstituted alkyl; Ris a C–Calkyl. The method includes the step of reacting a quaternary ammonium compound having the formula (NRRRR)X, wherein R, R, R, and Rare as defined above and X is Br or Cl, with a metal hydroxide in an aminoalcohol solvent to yield the quaternary ammonium hydroxide. The reaction forms metal bromide and/or metal chloride as a byproduct. The metal byproducts and excess metal hydroxide (if any) can be removed by methods known in the art. According to one preferred embodiment, the reaction of the quaternary ammonium compound with the metal hydroxide is performed in an anhydrous environment (i. e. , with no water present).
