D301 is an extremely durable macroporous  weak base anion exchange resin characterized by tertiary amine groups attached  to a styrene divinylbenzene copolymer matrix. It has a unique physical  structure which gives it superior kinetics and greater resistance to osmotic  shock than gel type weak base anion exchangers.

D301 yields exceptionally high operating  capacity on caustic soda regeneration and has low rinse requirements. It has a  higher resistance to organic matter than gel type anion exchangers.

D301 is supplied as moist spherical beads  in free base form, ready to use. D301 removes free mineral acid ions like  chloride, sulphate, nitrate etc. but will not remove weak acid ions like silica and carbon dioxide. In a demineralization system, D301 can be placed preceding  a strong base anion exchanger. This system offers a more economical  regeneration cost, as D301 operates at a very high regeneration efficiency in  comparison to strong base exchangers. Additional savings can be achieved by  regenerating the weak base and strong base exchangers in series. The design must, however take care to prevent silica precipitation on the weak base  exchanger. D301 placed preceding a strong base anion exchanger also serves to  protect it from organic fouling.

APPLICATIONS: D301 is suitable for demineralization of water for industrial steam  generation operated with co-current or modern counter-current systems. It is able  to remove high molecular weight organic materials from the influent water, thus  protecting a following strong base resin from fouling. The organics are readily  eluted, and the regenerated resin shows good rinse behavior, and a very  acceptable operating capacity on relatively high-TDS waters.
While there are several other  specially-tailored macroporous intermediate-base resins in the D301 series,  D301 itself is probably the most generally useful. A suitably-graded version,  D301MB is recommended for use in conjunction with 201 II type or 201x4 in layered-bed anion exchange systems.

PACKING:

 
CAUTION: Strong oxidizing agents like nitric acid  can cause explosive type reaction, when mixed with Ion Exchange resins.  Knowledgeable sources should be consulted in the handling of this material.

NOTE: Ion Exchange Resins are sold on a volume  basis, but are packed and shipped by weight. The shipping weight for each resin  is fixed & does not take into consideration the variations in density and  moisture content allowed within the product specifications. Therefore although  the weight of the material is constant, there may be slight variations in  volume, reflecting batch to batch variation of density and moisture content.

STORAGE  CONDITIONS: The resin  supplied in drums or bags should be stored in cool shed (warehouse) away from  direct sunlight & should be periodically damped down with clean water.
