Yellow glues

Allow the decomplexed oligomers to settle down in the flask as a yellow glue separate the supernatant by decanting or filtration on filter paper. These insoluble oligomers can be discarded.

Another green mixture is barhim chloride, 69 parts lactose, 30 pans shellac, i part. For a yellow light, a mixture of sodium nitrate, 20 parts sulphur, 20 pans antimony sulphide, 8 pans and carbon, a pans, may be tised. A mixture of powdered pitch, glue, and borax will give an mtense yellow flame.

Now make your little caterpillar. Cover two of the foam balls with the heads of the dried yarrow or other dried gold flower. The tops of these flowers should just poke into the foam balls, but you may need to add a little glue to the stems to secure them. If you live in an area where yarrow doesn t grow, then you can use other things, such as golden leaves or yellow goldenrod.

Di- -butyl phthalate is an odorless and colorless or faintly yellow oily liquid that does not occur in nature. It is a chemical that is added to hard plastics to make them soft. The plastics that di- -butyl phthalate is used most in are called polyvinyl chloride plastics and nitrocellulose lacquers. These plastics are used to make many products that we use every day such as carpets, paints, glue, insect repellents, hair spray, nail polish, and rocket fuel. In 1994, more than 17 million pounds (i.e., 7.8 million kilograms) of di- -butyl phthalate were made. 

MBOCA is a synthetic chemical used in industry primarily to produce castable polyurethane parts. It also has a coating application in chemical reactions to "set" glues, plastics, and adhesives. Since plastics have many uses, MBOCA is used very widely. Other names for MBOCA include 4,4 -methylenebis(2-chloroaniline), bis amine, DACPM, MCA, methylenebis ortho chloroaniline, and MOCA. The name MBOCA comes from methylene bis ortho chloro aniline. Pure MBOCA is a colorless solid, but MBOCA is usually made and used as yellow, tan, or brown pellets. If MBOCA is heated above 205°C, it may decompose. MBOCA has no odor or taste. Chapter 3 contains more information on the chemical and physical properties of MBOCA. Chapter 4 contains more information on its production and use. 

As pointed out by E. E. Free, by using very dil. soln. of lead nitrate and potassium chromate—say M- to JH-soln.— yellow colloidal solutions are obtained which are stable for some days and, it glue be present, the soln. are stable for many months. J. Milbauer and K. Kohn also found that in the presence of acetic acid, or when boiled, the colloidal lead chromate is flocculated. F. W. 0. de Coninck observed that when crystalline lead chromate is boiled for one-half to one hoim...
