Question

Верны ли следущие утверждения? 1Сырьем для производства искусственных волокон служит целлюлоза,получаемая из древесины ели и отходов хлопка. 2.Сырьем для производства синтетических волокон являются газы-продукты переработки каменного угля и нефти

Answer 1

1-нет, так как древесина натуральная
2-да, так как из нефти всегда синтезируют синтетику

Answer 2

Is the following statement true?

1. The raw material for the production of synthetic fibers is cellulose obtained from spruce wood and cotton waste.

The statement is partially true. Cellulose can be used as a raw material for the production of some types of synthetic fibers, but it is not the only source. Other sources of cellulose, such as bamboo, beechwood, and eucalyptus, can also be used. Additionally, some synthetic fibers are derived from petrochemicals rather than cellulose.

Is the following statement true?

2. The raw material for the production of synthetic fibers is gases produced from the processing of coal and oil.

The statement is partially true. Some synthetic fibers, such as nylon and polyester, are indeed derived from petrochemicals obtained from the processing of coal and oil. These petrochemicals are converted into monomers, which are then polymerized to form the synthetic fibers. However, not all synthetic fibers are produced from gases. Some synthetic fibers, like rayon and acetate, are derived from cellulose, as mentioned earlier.

To summarize, while cellulose obtained from wood and cotton waste can be used as a raw material for some synthetic fibers, other sources of cellulose and petrochemicals derived from coal and oil are also used in the production of synthetic fibers.
