Treatment of Polysilazane Waste

Abstract

The present invention provides for a method for treating polysilazane waste material.

1 . A process for treating polysilazane waste comprising contacting the polysilazane waste with a treatment stabilizer selected from the group consisting of an OH-containing compound and an OH-containing compound and alkaline mixture. 
   
   
       2 . The process of  claim 1 , wherein the contact of polysilazane waste and treatment stabilizer occurs by (a) injecting the treatment stabilizer into a waste stream of polysilazane waste; (b) adding the treatment stabilizer into a container containing polysilazane waste; or (c) adding the polysilazane waste into a container containing treatment stabilizer. 
   
   
       3 . The process of  claim 1 , wherein the treatment stabilizer further comprises a carrier solvent. 
   
   
       4 . The process of  claim 1 , wherein the treatment stabilizer is an OH-containing compound is selected from alcohols, ether alcohols, glycols, carboxylic acids, and mixtures thereof. 
   
   
       5 . The process of  claim 1 , wherein the OH-containing compound is selected from alcohols, ether alcohols, and mixtures thereof. 
   
   
       6 . The process of  claim 1 , wherein the treatment stabilizer is an OH-containing compound and alkaline mixture. 
   
   
       7 . The process of  claim 6 , wherein the OH-containing compound is selected from alcohols, ether alcohols, glycols, carboxylic acids, and mixtures thereof. 
   
   
       8 . The process of  claim 7 , wherein the OH-containing compound is selected from alcohols, ether alcohols, and mixtures thereof. 
   
   
       9 . The process of  claim 1 , wherein the treatment stabilizer is added to the polysilazane waste in a ratio of from about 1:2 treatment stabilizer:polysilazane waste to about 1:14 treatment stabilizer:polysilazane waste. 
   
   
       10 . The process of  claim 1 , wherein the treatment stabilizer is added to the polysilazane waste in a ratio of from about 1:4 treatment stabilizer:polysilazane waste to about 1:10 treatment stabilizer:polysilazane waste. 
   
   
       11 . The process of  claim 1 , wherein the treatment stabilizer is added to the polysilazane waste in a ratio of from about 1:6 treatment stabilizer:polysilazane waste to about 1:9 treatment stabilizer:polysilazane waste. 
   
   
       12 . The process of  claim 1 , wherein the treatment stabilizer is added to the polysilazane waste in a ratio of from about 1:7 treatment stabilizer:polysilazane waste to about 1:9 treatment stabilizer:polysilazane waste. 
   
   
       13 . A process for treating polysilazane waste comprising contacting the polysilazane waste with a treatment stabilizer solution wherein the treatment stabilizer solution comprises a carrier solvent and a treatment stabilizer selected from the group consisting of an OH-containing compound and an OH-containing compound and alkaline mixture. 
   
   
       14 . The process of  claim 13 , wherein the contact of polysilazane waste and treatment stabilizer solution occurs by (a) injecting the treatment stabilizer solution into a waste stream of polysilazane waste; (b) adding the treatment stabilizer solution into a container containing polysilazane waste; or (c) adding the polysilazane waste into a container containing treatment stabilizer solution. 
   
   
       15 . A treatment stabilizer for polysilazane waste selected from the group consisting of an OH-containing compound and an OH-containing compound and alkaline mixture. 
   
   
       16 . The treatment stabilizer of  claim 15 , wherein the treatment stabilizer is an OH-containing compound is selected from alcohols, ether alcohols, glycols, carboxylic acids, and mixtures thereof. 
   
   
       17 . The treatment stabilizer of  claim 16 , wherein the OH-containing compound is selected from alcohols, ether alcohols, and mixtures thereof. 
   
   
       18 . The treatment stabilizer of  claim 15 , wherein the treatment stabilizer is an OH-containing compound and alkaline mixture. 
   
   
       19 . The treatment stabilizer of  claim 18 , wherein the OH-containing compound is selected from alcohols, ether alcohols, glycols, carboxylic acids, and mixtures thereof.
