79 results about "Rubber seed oil" patented technology

Rubber seed oil is oil extracted from the seeds of rubber trees. In the latex manufacturing process, rubber seeds are not historically collected and commercialized. In Cambodia and other rubber manufacturing areas, rubber seeds are used to feed livestock. Although rubber seed is rich in nutrients, it also contains cyanogenic glycosides which will release prussic acid in the presence of enzymes or in slightly acidic conditions. Oil from the rubber seed is also of commercial importance. Hitherto, rubber seed has largely been allowed to waste with very little used for raising root stock seedlings for propagation purposes. The useful properties of the rubber seed oil make it similar to well-known linseed and soybean oil. Rubber seed oil also could be used for the paint industry as a semidrying oil, in the manufacture of soap, for the production of linoleum and alkyd resin; in medicine as antimalaria oil; and in engineering as core binder for factice preparation, and the cake left after oil extraction is used in fertilizer preparation and as feed for cattle and poultry. The potential of rubber wood as a source of timber is recognized in India, Sri Lanka, Indonesia, and Malaysia, with an increasing volume of sawn rubber wood used for furniture manufacturing and a variety of other applications.

The invention provides a method for determining the content of natural rubber in rubber seed oil. The determination method has the advantages of simple instrument and equipment, simple, convenient andquick operation, low detection cost and high accuracy and precision. The method for determining the content of the natural rubber in the rubber seed oil by adopting a saponification method is characterized by comprising the following steps: firstly, precisely weighing 100 to 200 grams of rubber seed oil sample and putting the rubber seed oil sample in a flask, adding potassium hydroxide into theflask to form 400 to 800 milliliters of alcohol solution, shaking up the solution and then connecting the solution to a reflux condensing tube, boiling the solution for about 1 to 2 hours in a water bath kettle, taking down the condensing tube, filtering the saponified solution to another flask while the solution is hot, crushing up rubber grains on a piece of filter cloth, washing the rubber grains till no alkali or soap is contained, finally kneading the rubber to form a slice, baking the slice with a vacuum oven (at the temperature of 80 DEG C) to constant weight and then weighing the slice, and calculating the content of the rubber. The rubber seed oil can be saponified in the alkali alcohol solution, the natural rubber belongs to a hydrocarbon substance and does not produce saponification effect, and the natural rubber is coagulated into the rubber grains to be separated out during the saponification of the rubber seed oil so as to determine the content of the natural rubber.
