Solubility wax

In architectural work, particular care must be taken to avoid destructive attack of the anodic film by alkaline mortar or cement during erection, and temporary coatings of spirit-soluble waxes, or acetate-butyrate lacquers are frequently applied to window frames and the like to protect against mortar splashes, which in any event should be removed at the earliest possible moment. 

Diverting agents assist in distributing acid more uniformly through the perforated formation interval (141). These are usually oil-soluble hydrocarbon resin particles. They may be dissolved by post-acid injection of xylene or similar solvents. Oil-soluble waxes, naphthalene, and solid organic acids such as benzoic acid have also been used (142). Best results are obtained using a broad range of particle sizes. 

The cuticle, being attached to the epidermal cells via a pectinaceous layer, can be released by disruption of this layer by chemicals such as ammonium oxalate/oxalic acid or by pectin-degrading enzymes. After treatment of the recovered cuticular layer with carbohydrate-hydrolyzing enzymes to remove the remaining attached carbohydrates, the soluble waxes can be removed by ex-... 

The first of these, utilized by Yoder, McCalip and Seibert,34 and by Balch, Broeg and Ambler,37 provides for the extraction of the aconitic acid from the sample being investigated, usually with diethyl ether, and the subsequent isolation of the acid from the solvent. In dealing with solid samples, e.g. alkaline earth aconitates, evaporator scale, etc., the prescribed procedure is to dissolve the material in aqueous mineral acid and to extract the acid solution exhaustively with ether. The ether extract is then evaporated under reduced pressure, the dried residue titrated with standard alkali and the titratable acid calculated as aconitic acid. In dealing with such solid samples it is often necessary to make an additional determination for oxalic acid which otherwise would be assumed to be aconitic acid.37 The aconitic acid in liquid samples is usually precipitated as the insoluble lead salt which is separated and treated as any other solid sample. In some cases this procedure is unnecessary and the liquid samples are merely acidified with a mineral acid and then extracted with ether.37 This method for the determination of aconitic acid, however, requires a considerable amount of time and is further complicated by the interference of ether-soluble waxes and non-volatile acids. 

TEXTILE WAX W is a water-soluble, wax-like, high-molecular polyether in the form of microbeads. It is dissolved by pouring warm water over the product. 

The SGC system incorporates a CAD system, resin systems for the photocurable resin, the soluble wax support and ionographic toner for creating photomasks, a vacuum wiping system, a UV curing system and a dewaxing machine. Important process variables are... 

Viscosity of soluble wax at 50% concentration is similar to heavy motor oil. The alcohol is significantly soluble in water. 

These wooden artifacts, such as digging implements and parts of old pig fences or house timbers, were recovered from the Papua New Guinea Highlands swamps in an excellent condition, with clear surface marks of their means of fabrication by stone axes. The choice of freeze-drying for this material in preference to the indifferent results expected from stewing the artifacts in cauldrons of hot water-soluble wax seemed reasonable at the time. The now-familiar response in wood to attempts at direct vacuum freeze-... 

Voxeljet Technology GmbH [39] offers a systems base on ink-jet dispensing of binder fluid onto particles, similar to the technology developed by MIT except the binder is not burned off after the part is printed. The build envelope is 85 cm x 45 cm x 50 cm. They also have a system that prints a water soluble wax that is ink-jet printed to form the boundary of a poured (in layers) wax part.

PROBLEM 14.7 Ethylene oxide can be polymerized by base to give carbo-wax, a water-soluble wax. Suggest a mechanism for the reaction. 

One may thus craft a Class III cosolvent process which removes a low molecular weight water-soluble wax used as a protectant for optic components — a highly valued deaning operation. 

Flooding the work with lubricant is recommended however, machines btiilt for flooding are equipped with a recirculating and filtering system and waterproof doth belts, and tiiey are expensive. An alternative is to spray a water-soluble wax fog throu atomizing nozzles on the fine of contact at both the entrance and exit sides of the belt. The solution should not be sprayed throu an ejector that mixes it wi air and increases the fire... 

Cuticle constitutes the boundary between higher plants and their environment. Therefore, this layer might be expected to play an important role in the interaction of the plant with environmental factors. The plant cuticle is composed almost entirely of lipids and the role of some of these lipids in the interaction between plants and microbes has become clear in the recent years. In this brief review, we shall confine our discussion to two specific examples of such interactions a detrimental one with pathogenic fungi and a beneficial one with phyllospheric bacteria which might provide fixed nitrogen in return for the use of some of the cuticular components as the carbon source. In this context, we will deal only with the role of the insoluble lipid-derived polymer, cutin, but not the role of soluble waxes that are always constituents of the cuticle. 

The outer surfaces of leaves are covered by a waxy cuticle which minimizes the loss of water from the plant and may act as a barrier to the uptake of agrochemicals, including herbicides. The cuticular membrane formed on the outer wall of the epidermal cells is composed of a framework of polymeric cutins in which are embedded cuticular waxes on the surface, soluble waxes are deposited to form epicuticular waxes. Carbohydrate fibers may extend into the cuticular membrane from the epidermal wall and middle lamella. In consequence, while the outer surface is essentially nonpolar, the inner region is relatively polar (Figure 8.1).
